Question

Chapter 21, Problem 020 GO Figure (a) shows an arrangement of three charged particles. 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 o relative to the positive direction of the x axis (see Figure (b). The curves in Figure (C) below give, for two situations, the magnitude Fnet of the net electrostatic force on particle A due to the other particles. That net force is given as a function of angle and as a multiple of a basic amount Fo. For example on curve 1, at 0 = 180°, we see that Fnet = 2Fo. (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? 6.7m6.7m A B C net 90° 1800 (a) Number Units (b) Number Units Show Work is REQUIRED for this question: Open Show Work
