In Fig. 13-34, three 5.00 kg spheres are located at distances d1 = 0.300 m and d2 = 0.400 m.

In Fig. 13-34, three 5.00 kg spheres
are located at distances d1 = 0.300 m and
d2 = 0.400 m. What are the (a) magnitude and (b) direction (relative
to the positive direction of the x axis) of the net gravitational force on
sphere B due to spheres A and C?
