1. The problem statement, all variables and given/known data A conducting spherical shell has a total net charge of +2 micro Coulombs. A point charge of Q = -3 micro coulombs is placed at the center of the sphere. What is the total net charge on the inner surface of the sphere? 2. Relevant equations coulombs law= kq1q2/r^2 3. The attempt at a solution I really have no idea where to start on this one even though I have a feeling it's actually really easy and I'm just missing something. I tried to find a similar problem in my physics book but didn't see anything, any help would be appreciated.
