Problem 2: The figure at left below shows a particle (A) that can move along the y-axis (out to infinite distance). Particles (B) and (C) are of equal mass, lie on the x-axis, and are equidistant from the y-axis. The distance D is 0.306 m. At right is a plot of the potential energy U of the three-particle system as a function of the position of A along the y-axis. The curve actually extends to the right and approaches the value of -2.7e11 J asymptotically as y. Determine the masses of all three particles. B 9A DD (a) (for-01)n T 10 3 0,5 y (cm) (6) 115
