Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +7q. Sphere B carries a charge of – 2q. Sphere C carries no net
charge. Spheres A and B are touched together and then separated.
Sphere C is then touched to sphere A, and separated from it. Last, sphere
C is touched to sphere B and separated from it. (a) How much charge
ends up on sphere C? What is the total charge on the three spheres (b)
before they are allowed to touch each other and (c) after they have
touched?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
