Problem 2.21 | Introduction to Electrodynamics (Griffiths)

A problem on finding the potential at any given point for a uniformly charged sphere. In Problem 2.21, Griffiths asks us to do this by integrating over the electric field. Later on in the book, you will find a different problem that tells us to find the same thing, though making use of the charge density instead of the electric field. At the start of the problem, I assume that you already know the electric field of a uniformly charged sphere. It can be derived easily enough using Gauss's Law. The numbering of this problem follows the 4th edition of Griffiths's textbook.
