Question 5 • Physics I

Which changes would result in a decrease in the gravitational force between two objects? Choose three correct answers.

Answer
A
decreasing the mass of one of the objects
B
increasing the mass of both objects
C
increasing the mass of one of the objects
D
decreasing the distance between the objects
E
increasing the distance between the objects
F
decreasing the mass of both objects

Explanation

The gravitational force follows F = Gm₁m₂/r², so it gets smaller if either object’s mass decreases or the distance between them increases. Decreasing the mass of one object (A) and decreasing the masses of both objects (F) reduce the force; increasing the distance (E) also reduces it. Increasing mass or decreasing distance would instead make the force stronger.
