Vedclass · Answer

(D) An equipotential surface is a surface where the electric potential is the same at every point.By definition,the work done $W$ in moving a charge $q$ from one point to another is given by $W = q(V_2 - V_1)$.Since the surface is equipotential,the potential at both points is equal,i.e.,$V_1 = V_2$.Therefore,$V_2 - V_1 = 0$.Consequently,the work done $W = q(0) = 0$.Thus,no work is done in moving a charge over an equipotential surface.

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