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 from the centre of sphere 1. If the net electric field at point P is zero and \[{{Q}_{1}}\]is \[64\mu C\], what is \[{{Q}_{2}}\]\[(in\mu C)\]
