Two asteroids exert a gravitational force, F, on each other. Some time later, the asteroids are now three times as far from each other as before. Which of the following represents the gravitational force at this distance?
|
|
F/3
|
|
|
F/2
|
|
|
F/6
|
|
|
F/9

Explanation:
Detailed explanation-1: -Two factors determine the magnitude of the gravitational force between two objects: (1) their masses and (2) the separation distance between them. The size of the force is proportional to the product of the masses of the two objects.
Detailed explanation-2: -Space. Each planet, moon and asteroid have their own gravitational pull defined by their density, size, mass, and proximity to other celestial bodies.
Detailed explanation-3: -Hence, when the distance between the objects is reduced to half, the gravitational force increases four times.
