← A charged rod is brought near a light ball that hangs from a thread, and the ball swings towards the rod. What can we say for sure about the ball?Sphere A has +14 µC and sphere B has -6 µC. The spheres are identical and made of metal. A touches B and they are separated. Then A touches a neutral sphere C of the same kind, and they are separated. What is the charge on C? →
