Consider two solid spheres of radius R with uniformly distributed charge throughout their volumes. Point 
P lies on the line connecting the centres of the spheres and is located at a distance of 0.5R from the centre 
of sphere 1 as shown. If the net electric field at P is zero, what is the ratio Q2/Q1 of the total charge on each 
sphere.
