Question

Four pairs of objects have the masses as described below, along with the distances between

them. Which pair of objects would have the greatest gravitational force between them? *
Mass of 1Kg and 1Kg, 2 meters apart
Mass of 1Kg'and 2Kg, 1 meters apart

Mass of 1 kg and 1 kg, 12 meters apart
Mass of 2 Kg and 1Kg, 12 meter apart

Answer 1

Mass of 1 Kg and 2 Kg, 1 meters apart.

Step-by-step explanation:

The gravitational force is defined as

`F=G(m_(1) m_(2) )/(r^(2) )`

By definition, the gravitational force depends directly on the product of the masses and indirectly on the distance between the masses, which means the further they are, the less gravitational force would be. And, the greater the masses, the greater the gravitational force.

Among the options, the pair that would have the greatest gravitational force is Mass of 1 Kg and 2 Kg, with 1 meter between them.

Notice that the last choice includes the same masses but with a greater distance between them, that means it would be a weaker graviational force.

Therefore, the right answer is the second choice.
