Two identical conducting spheres (#1 and #2) carry charges Q and 3Q respectively. They are separated by a distance r much larger than their diameters. Another identical conducting sphere (#3) is uncharged. Sphere #3 is first touched to #1, then to #2, and finally removed. As a result, the Coulomb force between #1 and #2, which was originally F, becomes: 1-7F/8 2-6F/15 3-3F/14 4-9F 5-7F/24
