Consider a solid conducting sphere with a radius 0.7 cm and charge ?7.3 pC on it. There is a conducting spherical shell concentric to the sphere. The shell has an inner radius 2.8 cm(with 2.8 cm > 0.7 cm) and outer radius 5 cm and a net charge 27.9 pC on the shell. Denote the charge on the inner surface of the shell by Q?2 and that on the outer surface of the shell by Q??2. Find the charge Q??2. Answer in units of pC
