1. The problem statement, all variables and given/known data A circular ring of charge of radius b has a total charge q uniformly distributed around it. The magnitude of the electric field at the center of the ring is: [Answer: 0] 2. Relevant equations 3. The attempt at a solution From the problem, do you just assume that the circular ring is a conductor? And since the charge is uniformly distributed, the conductor is in electrostatic equilibrium and there is no electric field? I'm not quite sure on how to think through it.
