Figure 21-29(a) shows an arrangement of three charged particles.Particles A and C are fixed on the x axis, but particle B can bemoved along a circle centered on particle A. During the movement, aradial line between A and B makes an angle θ relative to thepositive direction of the x axis (figure 21-29(b)). The curves infigure (c) below give, for two situations, the magnitude Fnet ofthe net electrostatic force on particle A due to the otherparticles. That net force is given as a function of angle θ and asa multiple of a basic amount F0. For example on curve 1, at θ =180o, we see that Fnet = 2F0. (a) For the situation correspondingto curve 1, what is the ratio of the charge of particle C to thatof particle B (including sign)? (b) For the situation correspondingto curve 2, what is that ratio?
Part A Curve 1: In the solution provided to this question F0=force of particle B on particle A and F is the force of particle Con particle A. We are given that Fnet=2F0 at θ=180*
How do we know that 2F0= F0-F? (Doesn't this meanthat F0=2Fo+F which doesn't make sense?)
Part B Curve 2: it is clear that the ratio ofFmax/Fmin = 1.25/0.75 What comes after that..the solution says:
5/3= (1+(1/4) qA/qC) / (1-(1/4)qA/qC)
what is the next step to simplify this and get a solution..?
