Question

Three identical conducting spheres initially have the following charges: 

A: 4Q

B: -6Q

C: 0Q

Sphere A and B are fixed in place, w/ a center-to-center separation that is much larger than the spheres. 

In experiment 1: C is touched to A, then separated and is touched by B, then removed. 

In experiment 2: C is touched to B, the separated and is touched by A, then removed. 

QUESTION: What is the ratio of electrostatic force between A and B at the end of experiment 2 to that at the end of experiment 1?
