Three dimensions. Three point particles are fixed in
place in an xyz coordinate system. Particle A, at
the origin, has mass mA. Particle B,
at xyz coordinates (3.00d, 2.00d,
4.00d), has mass 3.00mA, and particle
C, at coordinates (–3.00d, 3.00d,
–2.00d), has mass 3.00mA. A fourth
particle D, with mass 3.00mA, is to be
placed near the other particles. If distance d = 9.90 m,
at what (a) x, (b)
y, and (c) z coordinate should
D be placed so...
