EXAMPLE (based on problem 65 from page 641) A solid insulating sphere of radius a is uniformly charged with a total charge Q . It is surrounded by an concentric uncharged conducting spherical shell with an inner radius b and an outer radius c . (a) Find the electric field at r : (i) inside the insulating sphere ( r < a ) (ii) between the insulating sphere and the conducting shell ( a < r < b ) (iii) within the wall of the conducting shell ( b < r < c ) (iv) outside of the conducting shell (

Picture of Fields for sphere and shell in Example problem: Charge +Q on central charged sphere INDUCES:-Q on inside surface of conducting shell to eliminate electric field in conductor +Q on outside surface of conducting shell to maintain charge neutrality of shell The electric field outside is the same as if there were no conducting shell!...
