If charge +q is taken from one point to another over an equipotential surface, then
Options
- Awork done on the charge continuously increases.
- Bwork is done by the charge.
- Cwork done on the charge is constant.
- Dno work is done.
Correct answer
D. no work is done.
Step-by-step solution
The work done in moving a charge q from point A to point B is given by W = q(V_B - V_A) . For an equipotential surface, the electric potential at all points is the same, which means V_A = V_B . Therefore, the potential difference V = V_B - V_A = 0 . Substituting this into the work equation gives W = q 0 = 0 . Hence, no work is done in moving a charge over an equipotential surface. Answer: no work is done.
