Two point objects with different masses are kept at a distance R apart from each other. If the gravitational force between them is F, then:
Calculate the force of gravitation between two object of masses 80 kg and 120 kg kept at a distance of 10 m of each other.
Two bodies with same mass "m" separated by a distance "r" exert a gravitational force of F on each other. Suppose the distance between them is doubled and the force becomes F'. The ratio of two forces is
