Two spheres of masses m and M are situated in air and the gravitional force between them is F. The space around the masses is now filled with a liquid of specific gravity 3. The new gravitational force will be
A) F
B) \[\frac{F}{3}\]
C) 3F
D) \[\frac{F}{9}\]
Correct Answer:
A
Solution :
The gravitational force will remain the same as it is independent of density of medium.
