Two 700-kg masses (1543 Ib are separated by a distance of 40 m. Using Newton's law of gravitation,find the magnitude of the gravitational force exerted by one mass on the other.(Use G=6.6710-1N-m2/kg2
Newton's Law of Gravitation
The gravitational force between two objects is proportional to the mass of cach object and inverscly proportional to the square of the distance between the centers of the masses: Gm F
where G is a constant. The direction of the force is attractive and lies along the line joining the centers of the two masses fig.5.19.

m
figure 5.19 The gravitational force is attractive and acts along the line joining the center of the two masses. It obeys Newton's third law of motion F=-F).
