Two dimensions. In Fig. 13-35,
three point particles are fixed in place in
an xy plane. Particle A has mass mA, particle B has mass 2.00mA, and particle C has
mass 3.00mA. A fourth particle D, with
mass 4.00mA, is to be placed near the other
three particles. In terms of distance d, at what (a) x coordinate and (b) y coordinate should particle D be
placed so that the net gravitational force on particle A from particles B, C, and D is zero?
