1. The problem statement, all variables and given/known data

Please stop reading unless you have Griffiths E and M book.

In Example 3.8, Griffiths makes two claims without justification that I want justification for. First, he says that V=0 in the equatorial plane (I assume this means that x-y plane). Second, he says that [tex]V \to -E_0 r \cos{\theta}[/tex] for [tex]r >>R[/tex]. Where does the cosine come from?

2. Relevant equations

3. The attempt at a solution
