Introduction to Electrodynamics by David Griffiths, Problem 3.36

In my original uploading schedule, this should've gone up on 10/13. For the rest of this week I'll be playing catch up with my chapter three and chapter four videos, and then next week I should resume the original schedule (minus a week off) with chapter five. Hope it helps!
