Question

You have a solid, nonconducting sphere inside and concentric with ahollow conducting sphere.


The inner sphere has a radius R1 and uniform volume charge densityof ?; the outer sphere has a radius R2 and uniform surface chargedensity of s, and there is empty space between them. Note thatR1< R2. Use Gauss' Law to find the electric field in threeregions: a) Inside the inner sphere (r < R1), b) between them(R1 < r < R2), and c) outside the outer sphere (r > R2).Express your answers in terms of the charge density of each sphere(? and s ), the radii of the spheres (R1 and R2), and the distancer.
