Question: A conducting spherical shell has inner radius 2 / 3 R and outer radius R . ( a ) Suppose we put a charge Q

A conducting spherical shell has inner radius 2/3R and outer radius R.(a) Suppose we put a charge Q onthe shell (a conductor) so that all of the charge goes to the outer radius. Find the surface charge density(charge per area) of the sphere.Now suppose the shell is an insulator. (b) If the charge (Q) is uniformly distributed throughout itsvolume, find the volume charge density (charge per volume)
