1 PHYSICS 1996 PAPER (1.1/2 hr) The time given at the head of this paper is the time allowed for writing the answers. This question paper is divided into two Sections. Section I contains one question with ten parts (a) to (j); all ten parts are to be answered Section II contains six questions, numbered 2 to 7. You are to answer four of these questions The intended marks for the questions or parts of questions are given in the brackets SECTION -I (40 Marks) COMPULSORY: To be attempted by all candidates Q. 1. (a) (i) Explain briefly why a balloon filled with helium gas rises in air. Why does the balloon rise to a particular height above the ground and does not rise further? [2] Ans:(a) (i) The balloon filled with helium gas rises in air because the density of helium is less than the density of air. The density of air goes on decreasing as we go higher and higher above the surface of earth. A stage reaches when the upward thrust due to air is equal to weight of the helium filled balloon. At this height the balloon will be in equilibrium and does not rise further. Q. 1. (a) (ii) An iceberg floats in fresh water with a part of it outside the water surface. Calculate the fraction of volume of iceberg, which is below the water surface. Given: Density of ice = 917 kg m -3, Density of fresh water = 1,000 kg m -3 [2] Ans: (a) (ii) Let V be the total volume of iceberg and n be the volume below water. Then for the equilibrium of iceberg, Weight of iceberg = Weight of water displaced by immersed part of iceberg. Or V 917 g = ν 1,000 g Or ν = 917 = V 1,000 Thus part of volume will be below water. Q. 1. (b) (i) Relative density of silver is What is the density of silver in S.I. unit? [2] Ans: (b) (i) Density of silver on S.I. unit = ,000 = 10,800 kg m -3 Q. 1. (b) (ii) Diagram 1, given below, shows refraction and emergence of a ray of light incident on a rectangular glass slab. Copy the diagram and mark the lateral displacement of the incident ray. [2] Name the two factors on which the lateral displacement depends. Ans: (b)

2 (ii) The lateral displacement of the incident ray is KR as marked in the diagram. The lateral displacement depends upon (a) Thickness of the medium 't' (b) Refractive index of the medium for a given angle of incidence. Q. 1. (c) Two parallel rays of light enter the eye of a person suffering from myopia as shown in diagram 2 given below: [4] Copy the diagram and (i) complete the ray diagram to show where the image is formed; (ii) name the type of lens required to correct the defect; and (iii) draw the diagram again showing the position of the correcting lens, two parallel rays to the lens and the position of the final image. Ans: (c) (i) The image is formed in front of the retina. (ii) To correct the defect a CONCAVE lens or a divergent lens of suitable focal length is placed before the eye lens.

Using three rays starting from B and the properties of the points marked F1, O and F2, obtain the image formed by the lens. (F1 and F2 are the foci) [4] Ans: (d) Q. 1. (e) (i) Define a pair of complimentary colours. Name the colours in one such pair. [2] Ans: (e) (i) Any two colours which combine to produce white light are said to be Complimentary. Yellow and blue, red and peacock-blue or green and magenta, i.e., primary and the secondary opposite to it in the colour triangle are complimentary colours. Q. 1. (e) (ii) Fill in the blanks in the following: [4] (1) A red rose appears..when seen in green light. (2) Red + Blue =.. Ans: (e) (ii) (1) A red rose appears black when seen in green light. (2) Red + Blue = Magenta Q. 1. (f) (i) Define 1 watt and 1 kwh. [4] Ans: (f) (i) Watt. The unit of electric power is a watt. The power of an electric circuit is

3 one watt if it consumes energy of 1 Joule every second. Kilo-watt-hour. The kilo-watt-hour (kwh) is equal to the work done when a power of one kw is consumed for one hour. Thus Energy (in kwh) = watt hour = V (volt) I (amp) t (hours) 1,000 1,000 Q. 1. (f) (ii) Convert 1 kwh into Joules. Ans: (f) (ii) Relation between kilo-watt-hour and Joule. From definition, 1kWh = 1 kw 1 h = 1000 W 3600 s = 1000 J 3,600s s = 1,000 J 3,600 = 3,600,000 J = J Q. 1. (g) An electric bulb is marked 220 V, 100 W. The bulb is connected to a 220V supply. (i) Calculate: (1) Resistance of the filament; (2) Current flowing through the filament. [2] Ans: (g) (i) (1) Resistance R = V 2 = = 484W P 100 (2) Current I = V = 220 = A P 484 Q. 1. (g) (ii) Is the filament resistance of the glowing bulb greater, smaller or the same compared to its resistance when it is not glowing? [2] Ans: (g) (ii) The resistance of glowing filament is greater than the resistance of the filament when it is not glowing because the resistance increases with temperature. Q. 1. (h) There are three pins in an electric plug top. Answer the following: (i) How would you identify the earth pin? (ii) In which of the three connecting wires should a switch be connected? (iii) Explain why a switch should not be touched with wet hands. [4] Ans: (h) (i) The earth pin is thicker ; longer and at the centre. (ii) The switch is always connected in live-wire. (iii) The water on the hand forms a thin conducting layer which may conduct current from the switch to the hand thus giving a shock. Q. 1. (i) A given liquid changes into the gaseous state at a fixed temperature as well as at all temperatures. (i) Name the process that takes place in each of the above two cases. (ii) Mention two points of difference between the two cases in (i) above. [4]

4 Ans: (i) (i) The change of a liquid into gaseous state taking place at a fixed temperature is called ebullition or boiling. The fixed temperature is called the boiling point of liquid. Thus ebullition or boiling is the rapid change of a substance from the liquid to the gaseous state which takes place throughout the mass of the liquid and at a definite temperature. The change of liquid into gaseous state taking place at all the temperatures is termed as evaporation. When the liquid gradually passes into the gaseous state and the mass of the liquid is not disturbed and the change takes place at the surface of the liquid, then the process is known as evaporation. Thus evaporation is a slow change from the liquid to the gaseous state which takes place at the surface of the liquid and at all temperatures without disturbing the mass of the liquid. (ii) Other factors giving difference between Boiling and Evaporation. Boiling (i) It takes place at a definite temperature fixed for a given liquid (depending upon the pressure), by directly heating the liquid. (ii) It is a rapid process. (iii) During this process, the whole mass of the liquid is agitated. Evaporation (i) It takes place at all temperatures without heating the liquid directly. (ii) It is a slow process. (iii) It takes place only at the surface of the liquid. Q. 1. (j) State the energy changes which take place while using the following: (i) a microphone ; (ii) an electric bulb ; and (iii) a steam engine. [4] Ans: (j) (i) Sound energy is converted into electrical energy. (ii) Electrical energy is converted into light energy and heat energy. (iii) Heat energy is converted into mechanical and sound energy. SECTION-II Q 2. (a) (i) Define the S.I. unit of force. Obtain a relation between the S.I. unit and the C.G.S unit of force. (ii) A man of mass 60 kg runs up a flight of 30 steps in 15 seconds. If each step is 20 cm high, calculate the power developed by the man. Take g = 10 m s-2. (6) Ans. (a) (i) S.I. unit of force is Newton. One Newton force is said to be acting on a body of mass 1 kg if it produces in it an acceleration of 1 ms-2.

5 Thus 1 Newton = 1 kg 1 m s -2 = 1,000g 100 cm ss -2 = 105 g cm ss -2 = 105 dyne (ii) Power = Work = Increase in P.E.= mgh Time Time t = ( ) = 240 W 15 (b) (i) Define work and is S.I. unit. (ii) Write an expression for the work done by a constant force acting on a body which gets displaced from its initial position in a direction different from the direction of the force. (iii) Give an example when work done by a force acting on a body is zero even though the body gets displaced from its initial position by the application of the force. (4) Ans. (i) Work is said to be done when the point of application of a force moves through a certain distance in the direction of force. It is measured by the product of the force and the displacement of the point of application of the force in the direction of the force i.e. Work = Force displacement of point of application in the direction of force W = F. S S.I. Unit. If F = 1N and S = 1m, W = 1 N m = 1 Joule Thus one Joule of work is said to be done when the point of application of a force of 1 Newton moves through one metre in the direction of the force. (ii) When the constant force F acts making an angle? with the direction in which the body gets displaced, then work done is given by. W = FS cosθ (iii) If the angle between the force applied and the displacement is 900, work done W = FS cos 900 = FS 0 = 0 Examples. (a) Centripetal force acting on a body does no work as force is always directed at right angles to the direction of motion of the body. (b) A man walking along horizontal road and carrying a load on his head does not work against gravity. (c) A body crawling on a floor does no work in transporting his body. This is because the weight acts vertically and displacement is horizontal. Q. 3. (a) Diagram given below, shows an arrangement of four pulleys. A load L is attached to the movable lower block and effort E is applied at free end of the string. Copy the diagram and (i) Draw arrows to indicate tension in each part of the string; and (ii) Calculate the mechanical advantage of the system. (4)

6 Ans. (a) (i) In completed diagram (b) the arrow heads are marked to indicate the tension in each part of the string passing over the pulleys. (i) Let n be the number of segments of the string which supports the lower block then N = no. of the pulleys in two blocks = 4 As there is only one string passing round all the pulleys, the tension in each of the segment is the same i.e. T = E. Therefore, the total upward force on the block 4E and this must balance the weight L supported by it if the weight of lower block is neglected. Thus, L = 4E or L / E = 4 Now L / E is called the mechanical advantage of the system. Hence M.A = 4 (b) (I) Define specific heat capacity of a material. (ii) A 30g ice cube at 0 0 C is dropped into 20 0 g of water at 30 0 C. Calculate the final temperature of water when all the ice cube has melted. Given: Latent heat of ice = 80 cal g -1 ; Specific heat capacity of water = 1 cal g -1 (0C) -1. (6) Ans. (b) (I) The specific heat capacity of the substance is the quantity of heat required to raise the temperature of the unit mass of substance by one-degree celcius or one kelvin. On S.I. system, it is the quantity of heat required to raise the temperature of 1 kg of a substance through 1 0 C or 1K. Its units are J/kg/K or J kg -1 K -1. (ii) Let the final temperature be θ 0 C, then Heat gained by ice + Heat gained by water formed = Heat lost by water 30 X X 1 X θ = 200 X 1 X (300 - θ) 2, θ = 6, θ 230 θ = 3,600 θ = 3,600 = C 230 Q. 4. (a) (i) Define refractive index of a medium with respect to air. Calculate the speed of light in water. Given: Speed of light in vacuum = 3 X 108 m s -1, and Refractive index of water = 4. (ii) Calculate the power of a convex lens of focal length 25cm. (5) Ans. (a) (I) Refractive index of a medium with respect to air is defined as the ratio of velocity of

7 light in air to the velocity of light in the medium. U = Ca (velocity of light in air) Cm (velocity of light in medium) (ii) Here 4 = 3 X Cm Cm = 3 X 108 X 3 = 2.25 X 108 m s -1 4 (iii) Here Power P = 100 = 4 dioptres b) In the diagram 5 given below a source of light S is placed at the bottom of a beaker containing water. (i) Copy the diagram and show the path of rays, marked with arrows, after they meet the water-air boundary. (ii) Does the ray, marked with one arrow, undergo refraction? (iii) Name the phenomenon exhibited by the ray marked with three arrows. (iv) State the conditions necessary for the phenomenon in (iii) above. (5) Ans. (b) (i) The course of rays is shown in the figure (ii) No, this ray passes out normally without refraction. (iii) The ray gets reflected back into the same medium and phenomenon is called total internal reflection. (iv) Conditions necessary are (a) The ray must pass from denser to rarer medium. (b) The ray should be incident at an angle greater than the critical angle. Q 5 (a) (I) Define the phenomenon of resonance. (ii) A stretched wire 0.5 m long is made to vibrate in tow different modes shown in the given below. 1.

Give a reason for your answer. 3. In which case is the pitch of the note produced higher? Give a reason for your answer. (6) Ans. (I) Resonance is the phenomenon of forced vibration in which the body is set to vibrate with its natural frequency by another body whose frequency is exactly equal to this natural frequency. (ii) (1) The wavelength produced us 0.5 m. (Distance between three consecutive nodes.) (2) The intensity is directly proportional to square of amplitude. The amplitude of

8 wave in (A) is greater. Thus (A) gives louder sound. (3) Pitch of the note is directly proportional to frequency. (B) has greater frequency and hence greater pitch. (b) (I) A TV station transmits waves of frequency 200 MHz. Calculate the wavelength of the waves if their speed in air is 3.0 x10-8 m s -1. (ii) give the approximate range of wavelength in vacuum associated with U-V rays and visible light. (4) Ans. (b) (I) Frequency n = 200 MHz = 200 x 10 6 Hz Speed c = 3 x 10 8 m s -1 λ = c = 3 x 10 8 = 1.5 m n 200 x 10 6 (ii) For U-V rays, 100 Å to 3,800 Å is the range. For visible light, 3800 Å to 7,900 Å is the range. Q 6. (a) (I) Write an expression for the resistance of a conducting wire in terms of its length and area of cross-section. (ii) Two resistors of resistance 3 Ω and 2 Ω in parallel are connected to a cell of e.m.f. 1.5 V and internal resistance 0.3 Ω. Draw a labelled diagram showing the above arrangement and calculate the current drawn from the cell. (6) Ans. (a) (I) If R = resistance; l = length and A= area of cross-section. Then R = p.l/a where p = Resistivity or specific resistance (ii) The circuit is as shown in the figure. If the total resistance between A and B is R, then or 1 = 5 or R = 6 = 1.2 Ω R 3 2 R 6 5 Total resistance of the circuit = = 1.5 Ω Current I = 1.5 = 1.0 A. 1.5 (b) (i) Name the principle on which functioning of a transformer depends.
