Question

Two conducting spheres of radii R 1 and R 2 having charges Q 1 and Q 2 respectively are placed very far apart from each other. Now they are connected to each other by a connecting wire, then there is, no change in the energy of the system, an increase in the energy of the system, always a decrease in the energy of the system, a decrease in energy of the system unless q 1 R 2 = q 2 R 1
