23.39: a) The electric field outside the shell is the same as for a point charge at the center of the shell, so the potential outside the shell is the same as for a point charge: R. for 4 0 = r r πε q V The electric field is zero inside the shell, so no work is done on a test charge as

Unformatted text preview: it moves inside the shell and all points inside the shell are at the same potential as the surface of the shell: . for 4 R r R πε q V ≤ = nC 20 ) V 1200 ( ) m 15 . ( so b)-=-= = = k k RV q R kq V c) No, the amount of charge on the sphere is very small....
