### electrostatics...

potential inside a hollow conductor is the same at all points and is equal to that at its surface. This is true for all hollow conductors whether spherical, cylindrical or of any arbitrary shape. can anybody give me the proof of this statement?

Hint: The field inside the conductor is 0. Can you show this with gauss?

Otherwise the electrons will flow from areas with lower potential to that with higher potential

Sorry guys, I went through a chaos of changing and losing jobs.

I was not in the mood for mathematics.
