Consider two concentric conducting spheres. The outer sphere is hollow and initially has a charge -7Q on it. The inner sphere is solid and has a charge +2Q on it. a. How much charge is on the outer surface and inner surface of the outer sphere. b. If a wire is connected between the inner and outer sphere, after electrostatic equilibrium is established how much total charge is on the outer sphere? How much charge is on the outer surface and inner surface of the outer sphere? Does the electric field at the surface of the inside sphere change when the wire is connected? c. We return to original condition in (a). We now connect the outer sphere to ground with a wire and then disconnect it. How much total charge will be on the outer sphere? How much charge will be on the inner surface and outer surface of the outer sphere?

Two hollow concentric non-conducting spheres of radius the a and b (a gt b) contain charges Q_(a) and Q_(b) respectively. Prove that potential difference between the two spheres is independent of charge on outer sphere. If outer sphere is given an extra charge, is there any change in potential difference ?

A thick hollow metallic sphere of Inner and outer radius 2a and 4a, respectively, encloses a sold concentric metallic sphere of radius a'. These spheres are connected to the earth through switches S_1 and S_2 as shown in the figure First, switch S_1 is closed and after some time S_1 is opened. Then, S_2 is closed and after some time S_2 is opened. This completes one cycle. Initially, charge Q is given to the outer sphere with both S_1 and S_2 open. The charge on the inner sphere after n cycles of earthing the inner and outer spheres is
