Newton's Law of Gravitation

Two spheres of masses m and M are situated in air and the gravitational force between them is F. The space around the masses is now filled with a liquid of specific gravity 3. The gravitational force will now be

Show answer and solution

Answer: (b)

$F = \frac{GMm}{r^2}$ does not depend on the medium between the masses ( $G$ is a universal constant).
So filling the space with a liquid leaves the force unchanged.
So the answer is (b) $F$ .
