Answer:
c.Both the mass of the objects and the distance between them
Explanation:
The Law of Universal Gravitation states that the force of gravitational pull between objects is directly proportional to the product of the mass of both objects and indirectly proportional to the square of the distance between them.
This means that as the product of the masses increases, the force increases. On the other hand, as the distance between the objects increases, the force decreases.
It can be computed with the formula:
Where:
F = Gravitational force
M₁ = Mass of object 1
M₂ = Mass of object 2
r = distance between the center of the masses
G = gravitational constant (this is a fixed number so the pull is not dependent on this)
