According to Newton's universal law of gravitation, the force between two masses is
ADirectly proportional to the distance between them
BInversely proportional to the product of the masses
CDirectly proportional to the product of the masses
DIndependent of the masses involved
Answer & Solution
Correct answer: C. Directly proportional to the product of the masses
1. The law states F = G m₁m₂ / r².
2. So the force is directly proportional to the product of the two masses.
3. It is inversely proportional to the square of the distance between their centres.
4. Rule out option B: force depends on 1/r², not directly on distance.
