A capacitor consists of two conducting spheres of radii R1R_1 and R2R_2 (where R2>R1R_2 > R_1) separated by a large distance d≫R2d \gg R_2. The capacitance of this system can be approximated as two isolated spheres, each with capacitance 4πϵ0R4\pi\epsilon_0 R. If both spheres initially have zero charge and are then connected to opposite terminals of a battery with voltage VV, what is the approximate charge on the smaller sphere?
