In Prob. 2.25 you found the potential on the axis of a uniformly charged disk:

(a) Use this, together with the fact that Pl(1) = 1, to evaluate the first three terms in the expansion (3.72) for the potential of the disk at points off the axis, assuming r > R.

(b) Find the potential for r

V (r, 0) = -(r + R_r). 20
