The law of gravitation states that the gravitational force between two bodies of mass m1 and m2 is given by: 2 1 2 r F = Gm m G (gravitational constant) = 7 x10-11 Nm2 kg -2 r (distance between the two bodies) in the case of the Earth and Moon = 4 x 108 m m1 (Earth) = 6 x 1024 kg m2 (Moon) = 7 x 1022 kg What is the gravitational force between the Earth and the Moon?
