you are given three uncharged spherical conductors A,B and C touching each other .A glass rod carrying positive charge is briught near.What will be the charges on spheres A,B and C ?

Let charge on the rod is +Q
Due to induction, charge induced on any sphere is -Q.

All three spheres are in contact, due to conduction charge will be distributed equally on the each sphere.
Henec, net charge on each sphere is -Q/3.
