Question

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

Answer 1

By Universal law of gravitation,

F = \(\frac{Gm_1m_2}{r^2}\)

The force acting between two point masses m₁ and m₂, is independent of the nature of medium between them. Therefore, Gravitational force acting between two masses will remain unaffected when they are dipped in water.
