# Two uncharged, conducting spheres are separated by a distance d . When charge − Q is moved from sphere A to sphere B , the Coulomb force between them has magnitude F 0 . (a) Is the Coulomb force attractive or repulsive? (b) If an additional charge − Q is moved from A to B , what is the ratio of the new Coulomb force to the original Coulomb force, F new / F 0 ? (c) If sphere B is neutralized so it has no net charge, what is the ratio of the new to the original Coulomb force, F new / F 0 ?
