1. The problem statement, all variables and given/known data You are inside a large, hollow conductor that is isolated from the ground. There is a large charge on the conductor. If you touch the inside of it, will you be harmed? What if you had a charge with opposite sign of that on the conductor? 2. Relevant equations N/A 3. The attempt at a solution I think that if you are neutral, you will not be hurt since all the charge is on the outside. The second part confuses me. If you are charged, you will induce a charge on the inside surface of the conductor. So when you touch it, there will be a movement of electrons (i.e. current) which will hurt you, right? Or will there not be since you are not grounded and there's no reason for the electrons to go from the sphere to you or vice versa? Many thanks in advance!
