Two small positively charged spheres are suspended from a common point at the ceiling by the insulating light strings. The first sphere has mass $m_{1}$ and charge $q_{1}$ while the second one has mass $m_{2}$ and charge $q_{2}$ . The masses are in equilibrium. Match List-I with best possible entry in List- II.
