Example 4 : Extraneous charge is uniformly distributed over a dielectric sphere of radius R with volume density The dielectric constant is Find(a) the electric field as a function of r(b) the volume and surface densities of the bound charges. Hence, deduce that the total bound charges in the dielectric is zero. Solution : (a) …

Example 1 : A uniform isotropic dielectric is shaped as a spherical layer with radii a and b. Obtain the electric field as a function of distance r from the centre of layer, if the dielectric has a certain positive extraneous charge Q distributed uniformly (a) over the internal surface of the layer (b) over …
