The gravitational force between two objects is F. If the distance between them is doubled, the new force is:
A.F/2
B.F/4
C.2F
D.4F
Explanation
Core Concept
Newton's law of gravitation: F = Gm₁m₂/r². If r → 2r, then Fₙew = Gm₁m₂/(2r)² = Gm₁m₂/4r² = F/4. The force follows an inverse square law.
Correct Answer
BF/4
