You hold an apple in one hand and an orange in the other. If you doubled the mass of the apple and tripled the mass of the orange, without changing the distance between them, the gravitational force between them would be
A) unchanged, because it is zero both before and after the mass alterations.
B) five times larger.
C) six times larger.
D) three times larger.
E) doubled.

Question

Quizplus · Accepted Answer

The gravitational force between two objects is proportional to the product of their masses. If the mass of the apple is doubled and the mass of the orange is tripled, the product of their masses becomes six times larger, thus increasing the gravitational force by a factor of six.
