77. We note that r A (the distance from the origin to sphere A , which is the same as the separation between A and B ) is 0.5, r C = 0.8, and r D = 0.4 (with SI units understood). The force k F G that the k th sphere exerts on m B has magnitude 2 / kB k Gm m r and is directed from the origin towards m k so that it is conveniently written as () 23 ˆˆ ˆ ˆ =i + j = i + j . kB k k kk
