Figure shows three concentric conducting spherical shells with inner and outer shells earthed and the middle shell is given a charge `q`. Find the charge distribution of sphere

Figure - shows two conducting thin concentric shells of radii r and 3r The outer shell carries charge q where as inner shell is uncharged. Find the charge that will flow from inner shell to earth after the switch S is closed. [+q/3 charge will flow inner shell to earth]

Figure shows three concentric metallic spherical shells. The outermost shell has charge q_(2) , the inner most shell has charge q_(1) , and the middle shell is uncharged. The charge appearing on the inner surface of outermost shell is

There are three conducting and concentricspherical shells of radii R,2R and 3R. The charge on inner and outer most shells are q and 3q while middle shell is earthed. Find the ratio of number of field lines emitted by outermost shell and inner shell.
