1. The problem statement, all variables and given/known data Given a charged ring in 2-d, what is the e-field inside the ring? 2. Relevant equations Epoint = kq/r^2 3. The attempt at a solution This isn't a homework question, but more of a problem I keep running into whenever I think about it. I assumed it was 0. I came to this conclusion because the gradient of potential is electric field, and potential within a ring is constant, therefore electric field is 0.
