1. The problem statement, all variables and given/known data We are given two concentric conducting shells centered around a common origin. Within the inner shell there is a positive point charge q and somewhere outside the two shells is another positive point charge q. The question wants the field lines for this system and then again for the same system with a wire connecting the two conducting shells 2. Relevant equations I'm pretty sure I don't need any equations for this one. 3. The attempt at a solution What I have currently is in the attached photo. I'm nearly sure this is wrong though because they can't be the same can they? I don't really get how having two shells makes the first system any different than having one shell. If you wouldn't mind taking a look and telling me if i'm on the right track or not that would be great! Thank You!
