Proof of Electric Field Zero Inside Cylindrical Shell: Coulomb's Law

[kant]

Given an infinite long cylindrical shell of inner radias a and outer radius b.

proof using coulombs law that any point inside the inner radius a, the eletric field will always be zero.

no taker?

It's easy enough using Gauss's law. Coulomb's law is a little more difficult.

Of course, this assumes the cylinder is a conductor. If it isn't, the statement isn't necessarily true.

well, there is no fun if it is easy.
