Question

. Derive the following equation g = G x M/R^2 ​

Answer 1

Answer:

This derivation came from the Newton`s law of universal gravitation.

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. If we put into formula we get that: G*M*m ∝1/R^2. When get everything to RHS we get the formula: G*M*m/R^2.

Answer 2

Explanation:

As we know:-

Gravitational force=weight

GMm/R^2=mg

m will be cancelled and then

g =GM/R^2
