Problem 3 A spherical shell of dielectric material with inner radius a and outer radius b has a polarisation P(r) kr which is frozen into the material, and where k is a constant. As usual, r is the distance from the centre. There is no free charge 1) Calculate all the bound charges 2) Calculate the electric field inside the dielectric by first calculating the electric displacement D 3) Cross-check your result by using Gauss's law (i.e. for E without...
A thick spherical shell (inner radius a, outer radius b) is made of dielectric material with a "frozen-in" polarization P(r) 0 r<a P(r) ksin(0)/r r a<r<b where k is a constant, r is the distance from the center, and r is the radial unit vector. There is no free charge in the problem 1. Find expressions for all the bound (volume and surface) charge. Interpret with a diagram. 2. Determine the total bound charge.

A spherical shell has an inner radius of a and an outer radius of b. The shell is made of a dielectric material and has a polarization P f. The shell is neutral and there is no free charge. Determine the electric field in the three regions: (i) r < a; (i) a <r< b; and (ii) r > b using two different methods. (a) Determine the bound charges in each region and use Gauss' law to determine the electric...
