Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of -2.0 µC; sphere B carries a charge of -6.0 µC; and sphere C carries a charge of +4.0 µC. Spheres A and B are touched together and then separated. SpheresB and C are then touched and separated. Does sphere C end up with an excess or a deficiency of electrons and how many electrons is it?Select one:A. deficiency, 6 × 10^13B. excess, 2 × 10^13C. There is no excess or deficiency of electrons.D. excess, 3 × 10^13E. deficiency, 3 × 10^12

Answer:

None of the option is correct

A=-4µC, B=0 C, C=0 C

C will be +4.0 µC deficient after the contact

Explanation:

A and B are come in contact together, the charge will flow to establish  equilibrium, and hence becoming: A=-4µC, B=-4µC, C=+4.0 µC

Similarly when C and B touch, the positive and the negative will exact the same force due to equal charge magnitude and become electrically neutral : A=-4µC, B=0 C, C=0 C.
