7. In figure 6, two rings of radius R and R'=3/2R on the same plane with uniformly distributed charge of +Q on small circle. Point P on the central axis with a distance D=6/4R from the center of rings. What is the uniformly distributed charge (in Q) on R' radius centered ring if the net electric field at P is zero?
