A solid, insulating sphere of radius 1 cm has a charge of 10-7 C distributed uniformly over its volume. It is surrounded concentrically by a conducting thick spherical shell of inner radius 2 cm and outer radius 2.5 cm, which carries a net charge of -2 × 10-7 C. What is the electrostatic potential (in Volts) on the surface of the inner insulating sphere?
