Assume the sphere in Figure P17.52 is a piece of plastic (an insulator). How will that affect (change) the answer to Problem 52?

(reference problem 52)

Consider a metal sphere onto which a large number (suppose or more) of extra electrons is placed (Fig. P17.52). (a) Explain how these electrons will be distributed over the interior and the surface of the sphere. (b) Draw the electric field lines inside and outside the sphere.
