If the distance between two bodies is doubled the gravitational force between them becomes:
Correct answer: D. One fourth of the original value
- A. Half of the original value
- B. One third of the original value
- C. Doubled
- D. One fourth of the original value
Explanation
According to Newton's law of universal gravitation, the force of gravity between two objects is inversely proportional to the square of the distance between their centers. If the distance between two bodies is doubled, the gravitational force between them becomes one-fourth of the original force. This is because the force is inversely proportional to the square of the distance. So, if you double the distance between two bodies, the gravitational force between them decreases to one-fourth of its original value.

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.
