The free charge tends to be in its minimum potential energy state

(A) The electrostatic potential energy of a system of charges is given by $U = \frac{1}{2} \sum q_i V_i$. For a conductor,the charges experience mutual repulsion. To minimize the total electrostatic potential energy of the system,the charges move as far apart as possible. This configuration is achieved when the charges reside on the outer surface of the conductor. Therefore,the free charge tends to be in its minimum potential energy state.
