A solid insulating sphere of radius a = 3.9 cm is fixed at the origin of a co-or

Question

A solid insulating sphere of radius a = 3.9 cm is fixed at the origin of a co-ordinate system as shown. The sphere is uniformly charged with a charge density ? = -128 ?C/m3. Concentric with the sphere is an uncharged spherical conducting shell of inner radius b = 12.6 cm, and outer radius c = 14.6 cm.

What is V(c) - V(a), the potentital differnece between the outer surface of the conductor and the outer surface of the insulator?
