If a unit positive charge is taken from one point to another over an equipotential surface, then

Options

  1. Awork is done on the charge
  2. Bwork is done by the charge
  3. Cwork done is constant
  4. Dno work is done.

Correct answer

D. no work is done.

Step-by-step solution

Since the potential at each point of an equipotential surface is the same, the potential does not change while we move a unit positive charge from one point to another. Therefore work done in the process is zero.
