1. The problem statement, all variables and given/known data
This was on the 1982 AP Physics C E&M Free Response
10666
2. Relevant equations
Electric flux through a closed surface = (Charge enclosed)/epsilon_0
3. The attempt at a solution
This is the official solution given:
10667
I believe, however, that the electric flux must be undefined. The electric flux is the integral of E.dA. But since there are charges *on* (as opposed to inside) two of the points on the sphere, E at those points would be infinite. Thus, integral E.dA would be undefined.
Any help would be greatly appreciated.
Thank You in Advance.
