According to Newton's law of gravitation, force is_ _ proportional to the product of their masses:
Correct answer: A. Directly
- A. Directly
- B. Universal
- C. Inversely
- D. None of these
Explanation
According to Newton's law of gravitation, force is directly proportional to the product of the masses of two objects. The law is expressed mathematically as: F=Gm1m2/r2 where: ( F ) is the gravitational force between the two masses, (G) is the gravitational constant, (m1) and (m2) are the masses of the two objects, and (r) is the separation between the centers of the masses.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
