Your answer is partially correct. Figure (a) shows charged particles 1 and 2 that are fixed in place on an x axis. Particle 1 has a charge with a magnitude of 1911 = 18e.
Particle 3 of charge 93 = +18e 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 force 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 = 2.60 m. The plot
has an asymptote of F2net = 0.9094x 1025 Nas x As a multiple of e and including the sign, what is the charge 92 of particle 2?
