A Two parallel rings, each of radius R, are separated by a distance R. A positive charge^+Q is uniformly distributed around the upper ring and a negative charge^-Q is uniformly distributed around the lower ring. Let z be the vertical coordinate, with z = 0 taken to be the center of the lower negatively charged ring. What is the direction and magnitude of the electric field at the point A on the vertical axis, a distance...
I am not sure how to do a question like this, plz show the

MI.1. A thin circular plastic ring carries a net charge that is uniformly distributed throughout the ring with a linear density of λ 3.4 x 10-6 C/m. This ring is positioned parallel to a neutrally- charged infinite conducting plane such that its distance from the plane equals the radius (a) of the ring [Fig.1]. It can be shown that the magnitude...
