Three identical metal spheres A, B and C are supported on separate insulated stands and
placed in contact as shown in fig. A glass rod G is rubbed with silk and it is kept near the
sphere A
(A) What charge will there be on A, B and C ?
(B) The sphere C is earthed momentarily and then the glass rod is removed. What charge will there be on each sphere?

Explanation:

Three metal spheres A, B, and C are mounted on insulating stands. The spheres are touching one another, as shown in the diagram below. A strong positively charged object is brought near sphere A and a strong negative charge is brought near sphere C. While the charged objects remain near spheres A and C, sphere B is removed by means of its insulating stand. After the charged objects are removed, sphere B is first touched to sphere A and then to sphere C. The resulting charge on B would be of what relative amount and sign? (A) the same sign but 1/2 the magnitude as originally on sphere A (B) the opposite sign but 1/2 the magnitude as originally on sphere A (C) the opposite sign but 1/4 the magnitude as originally on sphere A (D) the same sign but 1/2 the magnitude as originally on sphere C (E) neutrally chargedRead more on Sarthaks.com - https://www.sarthaks.com/243075/three-metal-spheres-a-b-and-c-are-mounted-on-insulating-stands-the-spheres-are-touching
