Newton's law of gravitation states the force between two masses is:
ARepulsive
BProportional to distance
CAttractive, inversely proportional to square of distance
DIndependent of mass
Answer & Solution
Correct answer: C. Attractive, inversely proportional to square of distance
F = G m1 m2 / r². Always attractive, follows inverse square law. Direction along the line joining the centres.
