)find the potential away from the axis (i. e nonzero θ) , for distances r > r, by using the result above and fiddling with the legendre formula, griffiths’ boxed equation 3.65. you will in principle need an infinite sum of terms here - but for this problem, just work out explicitly what the first two non-zero terms are. (it might to remember that pl(1) is always equal to one, and you will have to think mathematically about how the formula above behaves for r > > r.) (b) look at your answer to part a, and compare i
