a 2. The volume between two concentric conducting spherical surfaces of radii a and b (a<b) is filled with a linear and inhomogeneous dielectric material of permittivity E = , /(1+kR), where k is a constant and R is the radial coordinate. A charge Q is placed on the inner surface, while the outer surface is grounded. Find: (a) The electric displacement in the region a<R<b. (6) The capacitance of the device. (c) The polarization in the region a<R<b. (d) The bound charge density of the device.
