Question
If one mass is doubled and the other mass is tripled without changing the distance, the gravitational force F between them becomes:
Correct Answer
Option B is the correct answer.
Detailed Explanation
The original force is F = Gm₁m₂/r². The new force F' = G(2m₁)(3m₂)/r² = 6 * (Gm₁m₂/r²) = 6F.
Hint
The force is directly proportional to the product of the masses.
