Question

Two objects of mass M and m are separated by a distance r. The gravitational force between the two objects quantitatively is ___ .

• A. $\frac{GmM}{r}$
• B. $\frac{GmM}{r^2}$
• C. $\frac{Gm}{r^2}$
• D. $\frac{G}{r^2}$

Answer 1

The correct option is B

$\frac{GmM}{r^2}$

Newton's law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Gravitational force = $\frac{GMm}{r^2}$
