Question

If the distance between two objects is doubled, the gravitational force between them becomes:
Options
A Four times the original force.
B Twice the original force.
C One-half the original force.
D One-quarter the original force.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Since force is inversely proportional to the square of the distance (F ∝ 1/r²), if r is doubled (r → 2r), then F becomes 1/(2r)² = 1/4r², which is one-quarter of the original force.

Hint

Recall the inverse square relationship.
