A conducting sphere carrying a charge ‘q' has a radius ‘a'. It is inside a concentric hollow conducting sphere of inner radius ‘b' and outer radius ‘c'. The hollow sphere has no net charge.
Calculate the electric field for:
a) r < a;
b) a < r < b;
c) b < r < c;
d) r > c;
e) What is the charge on the inner surface of the hollow sphere?
f) What is the charge on the outer surface?
