How is the gravitational force between two point masses affected when they are dipped in the water keeping the separation between them the same?
How is the gravitational force between two point masses affected when they are dipped in the water keeping the separation between them the same?

The gravitational force between point masses is unaffected by the medium and remains constant regardless of their surroundings. As a result, even if the two-point masses are submerged in water, the gravitational force between them stays unchanged.
