Three identical metallic uncharged spheres A, B and C of radius a are kept on the corners of an equilateral triangle of side `d (d gt gt a)`. A fourth sphere (radius a) which has charge Q touches A and is then removed to a position for away. B is earthed and then the earth connection is removed. c is then earthed. The charge on C is

Three identical metallic uncheged spheres A, B, and C, each of radius a , are kept at the corners of an equilateral triangle of side d(d gt gt a) as shown in (Fig. 3.137). The fourth sphere (of radius a), which has a charge q , touches A and is then removed a position far away. B is earthed and then the earth connection is removed. C is then earthed. The charge on C is .

Three charges +q, -q and +q are kept at the corners of an equilateral triangle of side d. Find the resultant electric force on a charge +q placed at the centroid O of the triangle.

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)

Three small conducting spheres each of radius a and charge q is placed at the corners of an equilateral triangle of side lenth /. The side lenth / is considerably larger than dimensions of the spheres. Find the electrical potential energy of system.

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
