A solid conducting sphere carrying charge q has radius a. It is inside a concentric hollow conducting sphere with inner radius b and outer radius c. The hollow sphere has no net charge.
Take V = 0 as r-> infinity. Use the electric field for this system:
to calculate the potential V at the following values of r.
A. r = c (at the outer surface of the hollow sphere)
B. r= b (at the inner surface of the hollow sphere)
C. r = a (at the surface of the solid sphere)
D. r = 0 (at the center of the solid sphere)
