7 KENDRIYA VIDYALAYA SANGATHAN, CHENNAI REGION HOLIDAY HOMEWORK CLASS: XII SUB: PHYSICS 1. Calculate number of protons in 1 coulomb of charge. 2. Two point charges q1 and q2 are placed close to each other. What is the nature of the force between the charges when q1q2<0? 3. Write down the value of absolute permittivity of free space. 4. How does the flux through spherical surface change if radius of the surface is doubled 5. A charge q is placed at the centre of a cube of side l. What is the electric flux passing through each face of the cube? 6. If the distance between two equal point charges is doubled and their individual charges are also doubled, what would happen to the force between them? 7. Plot a graph showing the variation of Coulomb force (F) versus (1/r 2 ), where r is the distance between the two charges of each pair of charges: (1µC, 2µC) and(2µc,-3µc). Interpret the graphs obtained. 8. Deduce an expression for the electric field at a point on an axial line of an electric dipole of length 2a. 9. Using Gauss theorem, obtain the expression for the electric field due to uniformly charged thin sheet of charge. 10. State Gauss theorem in electrostatics. Is electric flux a scalar or a vector? Give its SI unit. 11. Define the term electric dipole moment. Is it a scalar or a vector? Deduce an expression for the electric field at a point on the equatorial plane of an electric dipole of length 2a.(3) 12. Using Gauss theorem, obtain the expression for the electric field due to uniformly charged thin spherical shell of radius R at a point outside the shell. Draw a graph showing the variation of electric field with r, for r>r and r< R. 13. Derive an expression for the torque experienced by an electric dipole kept in a uniform electric field. Write the pair of vectors perpendicular to each other. 14. Using Gauss theorem, obtain the expression for the electric field due to uniformly charged linear conductor. 15. Calculate the electric field strength required to just support a water drop of mass 10-7 kg and having a charge 1.6x10-19 C. 16. (a)define electric lines of force. List any five properties of the electric lines of force (b) Two point charges of +16µC and -9µC are placed 8 cm apart in air. Determine the position of the point at which the resultant field is zero.

8 17. Two point charges q1 and q2 are placed close to each other. What is the nature of the force between the charges when q1q2>0? 18. Write down the relation between electric field and electric potential at a point Is the mass of a body affected on charging? 20. If the distance between two equal point charges is reduced to half and their individual charges are same, what would happen to the force between them? 21. Define capacitance of a capacitor. What are the factors on which capacitance of a parallel plate capacitor depends. 22. (a) Draw equipotential surfaces due to a point charge Q >0. (b) Are these surfaces equidistant from each other? If not, explain why. 23. (a) Define dielectric constant of a medium. (b) Force between two charges kept in air is F. What is the force between the same charges kept in water with same separation if the dielectric constant of water is 80? 24. Calculate the electric field strength required to just support a water drop of mass 10-7 kg and having a charge 1.6x10-19 C. 25. All numerical from the textbook chapter 1 & 2 to be solved. 26.
