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 q1q2R 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 10-7kg 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
