Chapter 13, Problem 12P

GO In Fig. 13-37a, particle A is fixed in place at x = −0.20 m on the x axis and particle B. with a mass of 1.0 kg, is fixed in place at the origin. Particle C (not shown) can be moved along the x axis, between particle B and x = ∞. Figure 13-37b shows the x component F_{net, x} of the net gravitational force on particle B due to particles A and C, as a function of position x of particle C. The plot actually extends to the right, approaching an asymptote of −4.17 × 10⁻¹⁰ N as x → ∞. What are the masses of (a) particle A and (b) particle C?
