Figure 21-33(a) shows charged particles 1 and 2 that are fixed inplace on an x axis. Particle 1 has a charge with a magnitude of|q1| = 19.0e. Particle 3 of charge q3 = +15.0e is initially on thex axis near particle 2.Then particle 3 is gradually moved in thepositive direction of the x axis. As a result, the magnitude of thenet electrostatic force on particle 2 due to particles 1 and 3changes. Figure 21-33(b) gives the x component of that net force asa function of the position x of particle 3. The scale of the x axisis set by xs = 1.40 m. The plot has an asymptote of F2,net = 2.543Ã 10-25 N as x ? 8. As a multiple of e and including the sign, whatis the charge q2 of particle 2?
