Question

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 |q₁| = 18e. Particle 3 of charge q₃ = +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 x_s = 2.40 m. The plot has an asymptote of F_2,net = 0.9519 × 10^-25 N as x → ∞. As a multiple of e and including the sign, what is the charge q₂ of particle 2?
