← 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?Two small spheres carry charges of 6 µC and 7 µC. They are 0.21 m apart in air. What is the force between them? →
