Consider three identical metal spheres A, B, and C. Sphere A carries a charge of -2.0gC, sphere B carries a charge of -6.0uC; and sphere C carries a charge of +5.0uC. Spheres A and B are touched together and then separated. Sphere B and C are then touched and separated. How much charge sphere C end up with?-3.0uC-4.0C +1.0uC+0.5 MC
