Answer 2

Explanation:

Newton's law of universal gravitation is usually stated as that "every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers."

Derivation:

F ∝ m.M

F ∝ 1/r²

By combining, we get,

F ∝ m.M/r²

To remove proportionality sign we need to add a proportionality constant.

Here the constant is G = 6.673 × 10^-11.

F = GmM/r²,

where F is the magnitude of the gravitational force and G is a proportionality factor called the gravitational constant. G is a universal gravitational constant—that is, it is thought to be the same everywhere in the universe.
