Newton's law of Gravitation states that the force of attraction between the two bodies is inversely proportional to:
Correct answer: C. Square of the distance between their centers
- A. Product of their masses
- B. Square of the distance between them
- C. Square of the distance between their centers
- D. Product of mass & distance between them
Explanation
F=GMm/R2 According to the formula, it is inversely proportional to the square of the separation of two bodies from their centers. Hence C is the correct option.

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.
