Question

The formula for the force between two objects is

F=GMm/r^2
,

where M and m are the masses of the two objects, G is a constant, and r is the distance between them. Solve the formula for G.

Here are the multiple-choice answers...

Answer 1

G = Fr² / Mm

Explanation:

Given:

F = GMm / r²

Where,

F = Force of the two objects

M = mass of object 1

m = mass of object 2

G = constant

r = distance between the objects

Solve the formula for G.

F = GMm / r²

Cross product

F * r² = GMm

Fr² = GMm

Divide both sides by Mm

G = Fr² / Mm
