1 Physics 6B Summer 2007 Final Question 1 An electron passes through two rectangular regions that contain uniform magnetic fields, B 1 and B 2. The field B 1 is stronger than the field B 2. Each field fills the region completely. How does the speed v 1 of the electron in region 1 compare with the speed v 2 in region 2? A. The speeds are the same in both regions. B. The speed v 1 is greater than v 2, because B 1 is stronger than B 1. C. The speed v 1 is less than v 2, because the radius of the circular path in region 1 is less than that in region 2. D. The speed v 1 is less than v 2, because the electron accelerates as it goes from region 1 to region 2. E. The speed v 1 is less than v 2, because B 1 is stronger than B 2. Question 2 Three particles are moving perpendicular to a uniform magnetic field and travel on circular paths (see the drawing). They have the same mass and speed. List the particles in order of their charge magnitude, largest to smallest. A. 3, 2, 1 B. 3, 1, 2 C. 2, 3, 1 D. 1, 3, 2 E. 1, 2, 3 Question 3 Suppose you want to produce a strong magnetic field that is constant in magnitude and direction in a region of space. Which one of the following would you choose to produce this field? A. The interior region of a long currentcarrying solenoid. B. The exterior region of a long currentcarrying solenoid. C. The region surrounding a long, straight, currentcarrying wire D. The region surrounding a loop of a currentcarrying wire. 1
2 Question 4 Three long, straight wires are carrying currents that have the same magnitude. In C the current is opposite to that in A and B. The wires are equally spaced. Each wire experiences a net force due to the other two wires. Which wire experiences a net force that has the greatest magnitude? A. A B. B C. C D. All three wires feel the same force Question 5 The drawing shows four situations in which two very long wires are carrying the samecurrent, although the direction of the currents may be different. The point P in the drawings is equidistant from each wire. Which one (or more) of these situations gives rise to a zero net magnetic field at P? A. 2 and 4 B. Only 1 C. Only 2 D. 2 and 3 E. 3 and 4 Question 6 Two different charges, q 1 and q 2, are placed at two different locations, one charge at each location. The locations have the same electric potential V. Do the charges have the same electric potential energy? A. Yes. If the electric potentials at the two locations are the same, the electric potential energies are also the same, regardless of the type (+ or ) and magnitude of the charges placed at these locations. B. Yes, because electric potential and electric potential energy are just different names for the same concept. C. No, because the electric potential V at a given location depends on the charge placed at that location, whereas the electric potential energy does not. D. No, because the electric potential energy at a given location depends on the charge placed at that location as well as the electric potential V. Question 7 A proton is released from rest at point A in a constant electric field and accelerates to point B (see part a of the drawing). An electron is released from rest at point B and accelerates to point A (see part b of the drawing). The distances traveled by the proton and the electron are the same. How does the change in the proton's electric potential energy compare with the change in the electron's electric potential energy? 2
3 A. The change in the proton's electric potential energy is the same as the change in the electron's electric potential energy. B. The proton experiences a greater change in electric potential energy, since it has a greater charge magnitude. C. The proton experiences a smaller change in electric potential energy, since it has a smaller charge magnitude. D. The proton experiences a smaller change in electric potential energy, since it has a smaller speed at B than the electron has at A. This is due to the larger mass of the proton. E. One cannot compare the change in potential energies because the proton and electron move in opposite directions. Question 8 Two identical resistors are connected first in series and second in parallel. The equivalent resistances of the two types of connections are, respectively, R S and R P. What is the ratio R S /R P? A. ¼ B. 4 C. ½ D. 1 E. 2 Question 9 The following four equations are supposed to result from applying Kirchhoff's rule to the circuit shown in the drawing. However, one of the equations is written incorrectly. Which one is it? A. I 1 = I 4 + I 5 B. I 3 = I 1 + I 2 C. I 6 = I 3 + I 5 D. I 2 = I 4 + I 6 3
4 Question 10 The drawings show a number of different possibilities for connecting an ammeter (AM) and a voltmeter (VM) to a circuit, in order to measure the current in and the voltage across the resistor labeled R 2. Which one of the possibilities shows the correct connections? A. B. C. D.: E. Question 11 Three capacitors are identical, each having a capacitance C. Two of them are connected in series. Then, this series combination is connected in parallel with the third capacitor. What is the equivalent capacitance of the entire connection? A. ½ C B. 1/3 C C. 3 C D. 2/3 C E. 3/2 C Question 12 A magnetic field is perpendicular to the plane of a flat coil. Since the magnitude of the field is increasing, an emf will be induced in the coil unless something is done to prevent it. Except for one option, all of the following are possible options that could be used to keep the emf at the zero level. Which option could not be used? A. Decrease the area of the coil. B. Increase the angle between the field and the normal to the plane of the coil. C. Simultaneously decrease the area of the coil and increase the angle between the field and the normal to the plane of the coil. D. Reduce the time interval during which the magnitude of the field increases. 4
5 Question 13 A long, vertical, straight wire carries a current I. The wire is perpendicular to the plane of a circular metal loop and passes through the center of the loop (see the drawing). The loop is allowed to fall and maintains its orientation with respect to the straight wire while doing so. In what direction does the current induced in the loop flow? A. There is no induced current. B. Around the loop from A to B to C to A C. Around the loop from C to B to A to C Question 14 The drawing shows a top view of two circular coils of conducting wire lying on a flat surface. The centers of the coils coincide. In the larger coil there is a switch and a battery. The smaller coil contains no switch and no battery. Describe the induced current that appears in the smaller coil when the switch in the larger coil is closed. A. It flows counterclockwise forever after the switch is closed. B. It flows clockwise forever after the switch is closed. C. It flows counterclockwise, but only for a short period just after the switch is closed. D. It flows clockwise, but only for a short period just after the switch is closed. Question 15 A point charge q is located at the origin. A charge q 0 can be placed at a point P 1, which is a distance r from the origin (top drawing). Or, a charge 2q 0 can be placed at P 2, which is a distance 2r from the origin (bottom drawing). All charges are positive. Which statement is true about the electric potentials at P 1 and P 2? A. The electric potential at P 1 is less than that at P 2, because q 0 is smaller than 2q 0. B. The electric potential at P 1 is less than that at P 2, because r is smaller than 2r. C. The electric potential at P 1 is greater than that at P 2, because r is smaller than 2r. D. The electric potential at P 1 is the same as that at P 2. 5
6 Question 16 Five volts is applied to two 2 ohm resistors in series. The resulting current is A. 5A B. 2.5 A C A D. 0.8 A E. 0.4 A Question 17 What is the charge on the 30µF capacitor in the Figure? A. 40 C B C C C D C Question 18 Mutual induction leads to an induced emf ε s in a secondary coil when a change ΔI P in the current in the primary coil occurs in a time Δt. The mutual inductance between the coils is M. The relative positions of the coils is then changed, after which a change of 2 ΔI P in the primary current in a time of ½ Δt is needed to produce the same induced emf ε s in the secondary coil. What is the mutual inductance with the coils in their new positions? A. ¼ M B. ½ M C. M D. 2 M E. 4 M Question 19 Inductor 1 stores the same amount of energy as inductor 2, although its inductance is only half the inductance of inductor 2. What is the ratio I 1 /I 2 of the currents in the two inductors? A B C D E
7 Question 20 Lines of magnetic field are A. Always straight lines B. Terminate on negative charges C. Point in the direction of the magnetic force exerted on a positive charge D.
