three identical metallic uncharged spheres A,B and C of radius are kept at the corners of an equilateral triangle of side d(d>>a). The fourth spheres (of radius a) which has a charge q touches A and is then removed to a position far away. B is earth and then the earth connection is removed. C is then earthed. The charge on C is______

zero..

 

let A get a charge of Q.. wen B is earthed it gets of -Q.. which is opposite to that of A..

 

so later wen C is earthed, it gets -Q due to A and +Q due to B... so net charge = 0000
