Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential inside the hollow conducting shell is found to be:

a) zero

b) uniform inside the sphere and equal to the electric potential on the surface of the sphere

c) smaller than the electric potential outside the sphere

d) varying as one over r squared.

Ans:

The electric potential inside the hollow conducting shell is determined to be uniform inside the sphere and equal to the electric potential on the surface of the sphere.
