A solid sphere of radius R has a charge `+2Q`. A hollow spherical concentric with the first sphere that has net charge -Q.

(a) Find the electric field between the spheres at a distance r from the centre of the inner sphere. `[R ltr lt3R]`
(b) Calculate the potential difference between the spheres.
(c) What would be the final distribution of charges, if a conducting wire joins the spheres?
(d) Instead of (c), if the inner sphere is earthed, what is the charge on it?
