(a) Calculate the potential V (r} for (i) r b. Take V = 0 at r = b.
(b) Show that the potential of the inner cylinder with respect to the outer is

(c) Use Eq. (23.23) and the result from part (a) to show that the electric field at any point between the cylinders has magnitude
E(r) = Vab/in (b/a) 1/r
(d) What is the potential difference between the two cylinders if the outer cylinder has no net charge?
