NEET 2003 Physics question
Two spheres of masses and are situated in air and the gravitational force between them is . The space around the masses is now filled with a liquid of specific density 3. The gravitational force will now be :
Answer: (2)
Solution
The gravitational force depends only on the two masses and the distance between them. Gravitation is not screened or modified by an intervening medium (unlike the electrostatic force, which depends
