Two identical balls having like charges and placed at a certain distance apart repel each other with a certain force. They are brought in contact and then moved apart to a distance equal to half their initial separation. The force of repulsion between them increases 4.5 times in comparision with the initial value. The ratio of the initial charges of the balls is

Figure (a) shows an arrangement of three charged particles separted by distance d. Particles A and C are fixed on the x-axis, but particle B can be moved along a circle centered on particle A. During the movement, a radial line between A and B makes an angle θ relative to the positive direction of the x-axis (Fig. b). The curves in Fig. c give, for two situations, the magnitude Fnet of the net electrostatic force on particle A due to the other particles. That net force if given as a function of angle θ and as a multiple of a basic amount F0. For example on curve 1, at θ=180∘ we see that Fnet=2F0. (a) For the situation corresponding to curve 1, what is the ratio of the charge of particle C to that of particle B (including sign)? (b) For the situation corresponding to curve 2, what is that ratio?
