There are two uncharged identical metallic spheres of radius a, separated a distance d. A charged metallic sphere (charge q) of sarue radius is brought and touches sphere 1. After some time it is moved away to a far off distance. After this, the sphere 2 is earthed. Find the charge on sphere 2.

There are two uncharged identicasl metallic spheres 1 and 2 of radius r separated by a distance d(dgtgtr) . A charged metalllic sphere of same radius having charge q is touched with one of the sphere. After some time it is moved away fom the system. Now, the uncharged sphere is earthed. Charge on earthed sphere is

There are two uncharged identicasl metallic spheres 1 and 2 of radius r separated by a distance d(dgtgtr) . A charged metalllic sphere of same radius having charge q is touched with one of the sphere. After some time it is moved away fom the system. Now, the uncharged sphere is earthed. Charge on earthed sphere is

There are three unchanged identical metallic spheres 1,2 and 3 each of radius r and are placed at the verticles of an equlilateral triangle of side d .A charged metallic sphere having equal q of same radius r is touched to sphere 1 after some time it is taken to the location of sphere 2 and is touched to it ,then it is taken far away form sphere 1,2,3 after that the sphere 3 is grounded the charge on sphere 3 is (neglect electrostatic induction by assuming d gt gt 2r)
