Four 7.5 kilogram spheres are placed at the corners of a square of side 0.65 meter.
(a) Find the magnitude of the gravitational force exerted on one sphere which is in left and down corner of the square by the other three.
(b) Find what is its direction? Suppose that x-axis is directed to the right.
A bowling ball (mass = 7.2 kg, radius = 0.14 m) and a billiard ball (mass = 0.47 kg, radius = 0.028 m) may each be treated as uniform spheres. What is the magnitude of the maximum gravitational force that each can exert on the other?
