The range through which the gravitational force acts is:
Correct answer: C. Extremely long
- A. Limited to 1 x 10^-10 m
- B. Limited to 1 x 10^-2 m
- C. Extremely long
- D. about 1 x 10^5 m
Explanation
F =GMm/ r 2 , So this shows that F can be 0 only when the distance is infinite, proving that Gravitational forces have an extremely long range. So the correct option is C.

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.
