Two concentric rings, one of radius R and total charge +Q and second of radius 2 R and total charge −8–√Q, lie in x−y plane (i.e., z = 0 plane). The common centre of rings lies at origin and the common axis coincides with z-axis. The charge is uniformly distributed on both rings. At what distance from origin is the net electric field on z-axis zero?
