Two dimensions. In the gure, three point particles are xed in place in an )0; plane. Particle A has mass m; = g, particle B has mass 2.00mA, and particle C has mass 3.00mA.A fourth particle D, with mass 400mg, is to be placed near the other three particles. At what {a} x coordinate and lb} y coordinate should particle D be placed so that the net gravitational force on particle Afrom particles B, C, and Dis zero (d= 25 cm)? [a] Number i {b} Number
