A solid conducting sphere, having a radius a and surface charge density of o, is located inside a hollow conducting shell of radius b.

Question

A solid conducting sphere, having a radius a and surface charge density of o, is located inside a hollow conducting shell of radius b.

a) Use Gauss's law to show that the magnitude of the electric field at r is given by E= (sigma*(a)^2)/(epsilon*(r)^2) where a < r < b.

b) What is the electric field at r < a?

Answer 1

E=yqr/a3 the electric field in this region
