Charge Distribution on a Conducting Shell
A hollow conducting spherical shell with inner radius a and outer radius b carries a net charge of -3q. If a point charge +q is placed at the center of the shell, what is the charge distribution on the shell in electrostatic equilibrium?
A
-2q on inner surface, -q on outer surface
B
-3q on outer surface only
C
-q on inner surface, -2q on outer surface
D
-3q distributed uniformly throughout the shell
