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