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
- A3 F
- BF
- CF/3
- DF/9
View written solutionFree
Correct answer: B
Gravitational force is independent of medium, Hence, this will remain same.
