Question

10. Two uncharged, conducting spheres, A and B, are held at rest on insulating stands and are in contact. A positively charged rod is brought near sphere A as suggested in the figure. While the rod is in place, someone moves sphere B away from A. How will the spheres be charged, if at all? Sphere A Sphere B A) positive positive B) positive negative C) negative positive D) negative negative E) zero zero 11. Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of -2.0 ?C; sphere B carries a charge of -6.0 ?C; and sphere C carries a charge of +4.0 ?C. Spheres A and B are touched together and then separated. Spheres B 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? A) deficiency, 6 × 10^13 B) excess, 3 × 10^13 C) excess, 2 × 10^13 D) deficiency, 3 × 10^12 E) There is no excess or deficiency of electrons. 12. Two charged particles A and B are located near one another. Both the magnitude and direction of the force that particle A exerts on particle B is independent of A) the sign of charge B. B) the sign of charge A. C) the distance between A and B. D) the magnitude of the charge on B. E) The magnitude and direction of the force are dependent on all of the above choices.
