Vedclass · Answer

(A) Statement $(A)$ is true: Inside a charged hollow metal sphere,the electric field $E$ is $0$ because there is no charge enclosed. However,the electric potential $V$ is constant and equal to the potential at the surface,so $V 
eq 0$.Statement $(B)$ is true: By definition,an equipotential surface is a surface where the potential is the same at all points. Since work done $W = q(V_f - V_i)$ and $V_f = V_i$,the work done is $0$.Statement $(C)$ is true: When two like charges are brought closer,they repel each other. To move them closer,external work must be done against the electrostatic repulsive force. This work is stored as an increase in the mutual electrostatic potential energy of the system.Therefore,all three statements are correct.
