Questions for Practice
  1. Net capacitance of three identical capacitors connected in parallel is 12 microfarad. What will be the net capacitance when two of them are connected in (i) parallel (ii) series?
  2. A charge Q is distributed over a metal sphere of radius R. What is the electric field and electric potential at the centre? Answer: E = 0, V = kQ/R.
  3. Write the ratio of electric field intensity due to a dipole at a point on the equatorial line to the field at a point at a point on the axial line, when the points are at the same distance from the centre of dipole.
  4. An uncharged conductor A placed on an insulating stand is brought near a charged insulated conductor B. What happens to the charge and potential of B?
  5. In an uniform electric field of strength E, a charged particle Q moves point A to point B in the direction of the field and back from B to A. Calculate the ratio of the work done by the electric field in taking the charge particle from A to B and from B to A.
  6. How does the relaxation time of electron in the conductor change when temperature of the conductor decreases.



Important Questions
  • Why is the potentiometer preferred to a voltmeter for measuring emf of a cell?
  • A copper wire of resistance R is uniformly stretched till its length is increased to n times its original length. What will be its new resistance?
  • A car battery is of 12V. Eight dry cells of 1.5 V connected in series also give 12V, but such a combination is not used to start a car. Why?
  • An oil drop of mass m carrying charge –Q is to be held stationary in the gravitational field of the earth. What is the magnitude and direction of the electrostatic field required for this purpose? Answer: E = mg/Q, downward.
