In the gure three identical conducting spheres initially have the following charges: sphere A, BID; sphere B, 9Q; and sphere C, CI. Spheres A and B are xed 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 sphereA 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 ofthe electrostatic force between A and B at the end of experiment 2 to that atthe end of experiment 1? 3:4 (1 ~: Number n Units v
