1) Assume we have a thin conducting ring (radius R) that is uniformly charged with net charge Q. We're going to derive an equation for the electric field along the axis going through the center of the ring. Choose the z axis to coincide with the axis extending vertically through the middle of the ring. R ith "bit" Charged ring (Image from textbook by T.A. Moore) a) Explain why the net electric field at the center of the ring (in the plane of the ring) is zero b) We want to slice the ring into tiny charged "bits".
