Vedclass · Answer

(D) For a conducting sphere,the charge resides on the surface.In the absence of an external electric field,the charge is distributed uniformly over the surface due to mutual repulsion.However,the property that the entire conductor is an equipotential volume (and thus the surface is an equipotential surface) holds true regardless of the presence of an external electric field.Therefore,the potential at every point on the surface of the conducting sphere must be the same.
