• Three bodies of masses m1, m2 and m3 are in a straight line and m1 is between
m2 and m3. Represent the interactions on a force diagram
gravitational forces that act on each one of them.
• Three bodies of masses ma, mb and mc lie at the vertices of a triangle
equilateral represent the interactions on a force diagram
gravitational forces that act on each one of them.
