3. A thick spherical shell (inner radius a, outer radius b) is made of dielectric material with a 'frozen-in' polarization k P(r) -F, where k is a constant and r is the distance from the center. There is no free charge here. Find the electric field in all three regions by: (a) Locating all the bound charge and use Gauss's law to calculate the field it produces. (15/100) (b) Finding D first, and then calculate E by using equation D = €0E+P. (5/100)
