Question: A long, thin, nonconducting plastic rod is bent into a loop with radius R. Between the ends of the rod, a small gap of length

A long, thin, nonconducting plastic rod is bent into a loop with radius R. Between the ends of the rod, a small gap of length l ( l << R) remains. A charge Q is equally distributed on the rod.

(a) Indicate the direction of the electric field at the center of the loop.

(b) Find the magnitude of the electric field at the center of the loop.
