I uploaded a file that gives the problem statement.
I don't believe any equations are necessary. However, I could be wrong. I believe it to be a concept question. The relevant concept being that the electric field inside conducting materials in equilibrium is equal to zero.[/B]
The Attempt at a Solution
I am not feeling super confident but here is my attempt:
A, C,D,E,F all zero. and B = -1uC
If I am way off base just say so and I will give the problem a few more brain cycles. If there is a relevant equation that I am missing please let me know.
