Two isolated metallic solid spheres of radii R and 2R are charged, such that both of these have same charge density. The spheres are located far away from each other and connected by a thin conducting wire. Find the new charge density on the bigger sphere.

A small sphere of radius a carrying a positive charge q, is placed concentrically inside a larger hollowconducting sheli of radius b (bgt a). This outer shell has charge Q on it. Show that if these spheres are connected by a conducting wire, charge will always flow from the inner sphere to the outer sphuisirrespective of the magnitude of the two charges.
