Two concentric conducting spherical shells of radii R and 2R having charges A and B and potential 2v and 3v respectively Now shell B is earthed by closing switch S Let charges on spherical shells A B become q A q respectively then DA 96 magnitude A B 1 magnitude potential of A after earthing becomes 3v 2 potential difference between A and B VA VB after earthing becomes 2 k
