Problem
Three identical small conducting spheres A, B, and C are mounted on insulating stands so they can be touched together in any sequence without losing charge to the surroundings.
Initially, sphere A carries +12nC, sphere B carries −6nC, and sphere C is neutral. The following sequence of operations is performed:
(a) After step 1, determine the charge on each of spheres A and B.
(b) After step 2, determine the charge on each of spheres B and C.
(c) After step 3, determine the final charge on each of spheres A, B, and C.
(d) For the entire three-step process, compute the net number of electrons that moved onto or off of sphere C. Indicate whether electrons entered or left sphere C overall.
(e) Discuss how the results you obtained demonstrate conservation of electric charge for the three-sphere system throughout the entire sequence.
