1. Assume a ring of radius a, charge Q. Find the work done to assemble the ring.
2. W=U=.5*sum(kqq'/r) for all charge elements
3. I know that this is equal to the potential energy of the system of charges. I attempted to take half the double integral dq dq'/r(q,q') from 0 to Q but this proved to be excessively complicated and confusing. After that I became lost.
