Coulomb’s force law
Two identical small metal spheres are separated by 1.0 X 105 m and exert an 18.9-N repulsive force on each other. A wire is connected between the spheres and then removed. The spheres now repel each other, exerting a 22.5-N force. (a) Explain why the force that these two objects exert on each other changed. (b) Determine everything you can about the situation before the wire was connected and after it was removed.
