In the plane z=5 there is a ring with a 3cm radius with its center on the z axis. The ring has a uniformly distributed charge Q. The origin 0,0,0 is at a small sphere with a mass of 0.5kg and a charge of -Q. Find the electric field at the origin in terms of Q without taking into consideration the sphere.
