Two isolated metallic solid spheres of radii R and 2R are charged such that both of these have same charge density σ. 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.

b and c are shown in (Fig. 3.100). Charge on the shell of radius b is Q. If the key K is closed find the charges on the innermost and outermost shells and the radio of charge densities of the shells. Given that a:b:c=1:2:3. Three concentric conducting shells of radii a
