Two identical conducting spheres labeled A and B have net charges q1 = 4 q. (>0) and q2 = -6 9o, respectively. A third conducting sphere identical to the others is initially uncharged. This third sphere is touched first to the first sphere and then to the second sphere before being removed from the area. The net charge on the second sphere will now be x 9o.
