Electrostatics

Physics

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

ans is 35.2pc....the solid sphere inside the shell acts as a point charge...since the field inside the conductor should b zero,the inner surface of the shell develops a negative charge of 7.3pc...the shell already has a charge of 27.9pc,since charge should b conserved the charge that appears on the outer shell is 27.9+7.3=35.2pc
