Figure (a) shows charged particles 1 and 2 that are fixed in place on an x axis. Particle t has a charge with a magnitude of |q1| = 8.00e. Particle 3 of charge q3 = + 8.00e is initially on the x axis near particle 2. Then particle 3 is gradually moved in the positive direction of the x axis. As a result, the magnitude of the net electrostatic forces F2net on particle 2 due to particles 1 and 3 changes. Figure (b) gives the x component of that net force as a function of the position x of particle 3. The scale of the x axis is set by xs = 0.80 m. The plot has an asymptote of F2net = 1.5 x 10-25 N as x ? ?. As a multiple of e and including the sign, what is the charge q2 of particle 2?
