What (a)x & (b) y coord should particle D be placed so that the net gravitational force on particle A from particles B, C, & D is 0 ?
Information Given: Two dimensions. In the figure, three point particles are fixed in place in an xy plane. Particle A has mass mA = 3 g, 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.
Question: 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 (d = 22 cm)?
I've seen several ways to do it and I've attempted them but still continue to get the wrong answer as I do not understand this very well. Particle A having 3g is also throwing me off.
Help Please!
Thank You!
