Check my work (electrodynamics)
I found an old exam by my professor. this is the question.
 here is my solution using Spherical Harmonics  in case it's hard to read Vin = Q/2pi * 1/(e1 +e2) *1/a Vout = Q/2pi * 1/(e1 +e2) *1/r

oops, I forgot the
.n^ when finding sigmaAB and sigmaAC but since there is no theta or phi dependence it works out the same.

Nobody's awake yet, Crosscountry, and sunday nights are always a bit slow. I'd suggest giving it another 18 hours or so.

nevermind. my inside potetential was wrong.
I needed to take into account that the charges weren't evenly distributed.
