A spherical conductor of radius RR has nonet charge on it. However, there is a cavityinside it of radius aa and concentric withthe conductor and there is a point charge,+Q+Q, in the centre of that cavity. Thesituation is shown in the figure below.R+QTake R=20.0 cm, a=10.0 cm and Q=7.50 µC.(a) What is the surface charge density ofthe induced charge on the inner surface ofthe conductor?(b) What is the surface charge density ofthe outside surface of the conductor?

To find the surface charge density of induced charge, we use gauss law.
