In the figure below, three point particles are fixed in place in an xy plane. Particle A has mass mA, particle B has mass 2.35mA, and particle C has mass 3.45mA. A fourth particle D, with mass 4.40mĄ, is to be placed near the other three particles. In terms of distance d, at what coordinates should particle D be placed so that the net gravitational force on particle A from particles B, C, and D is zero? (a) č 1.5d x coordinate d (b) y coordinate d Bo A d x
