Gravitational force in a liquid medium – Rankers Physics

Newton's Law of Gravitation: Practice Problem & Solution

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 density $c$. The gravitational force will now be: (2003)
$3F$
$F$
$\frac{F}{3}$
$\frac{F}{9}$

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Newton's Law of Gravitation. Understanding the underlying formula is key to arriving at the correct answer below:

The gravitational force between two point masses is completely independent of the intervening medium. Therefore, the force remains $F$ even when the space is filled with a liquid.
