The force of gravity between two objects is proportional to the
A) difference of their masses.
B) product of their masses.
C) ratio of their masses.
D) sum of their masses.

Question

Quizplus · Accepted Answer

According to the universal law of gravitation, the force of gravity between two objects is directly proportional to the product of their masses (F ∝ m1m2). Therefore, the correct choice is (B) product of their masses. The difference, ratio, or sum of their masses is not directly related to the force of gravity between two objects.
