A solid conducting sphere having charge Q is surrounded by an uncharged concentric conducting hollow spherical shell. Let the p.d. between the surface of the solid sphere and that of the outer surface of hollow shell be V. If now shell is given a charge - 3 Q, the new p.d. between the same two surfaces is
V 2V 4 V - 2V
