Figure shows, in cross section, two solid spheres with uniformly distributed charge throughout their volumes. Each has radius R. point P lies on a line connecting the centres of the spheres, at radial distance r/2.00 from the centre of sphere 1 . If the net electric field at point P is zero what is the ratio q2 / q1 of the total charges ?
