In Fig. 21-24, three identical conducting spheres initially have the following charges: sphere A, 4 Q ; sphere B , −6 Q ; and sphere C , 0. Spheres A and B are fixed in place, with a center-to-center separation that is much larger than the spheres. Two experiments are conducted. In experiment 1, sphere C is touched to sphere A and then (separately) to sphere B , and then it is removed. In experiment 2, starting with the same initial states, the procedure is reversed: Sphere C is touched to sphere B and then (separately) to sphere A , and then it is removed. What is the ratio of the electrostatic force between A and B at the end of experiment 2 to that at the end of experiment 1? Figure 21-24 Problems 8 and 65.
