(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two arbitrarily thin concentric coplanar rings of radius a and 2a carry uniformly distributed charge density -Q_{e}and [tex]\sqrt{27}[/tex]Q_{e}, respectively.

Assuming that Z axis coincides with the rings' axes, and that the plane of the rings correspond to z=0, determine the location of all points of equilibrium(ie zero E field).

2. Relevant equations

3. The attempt at a solution

Need some hint.
