If the distance between Sun and Earth is made two third times of the present value, then gravitational force between them will become
Correct option is: (D) \(\frac{9}{4}\) times Gravitational Force \(F = \frac{G \ m_1m_2}{r^2}\) \(\frac{F_2}{F_1} = \left(\frac{r_1}{r_2}\right)^2\) \(\frac{F_2}{F_1} = \left(\frac{r_1}{\frac{2}{3}r_1}\right)^2\) \(\frac{F_2}{F_1} = \frac{9}{4}\) \(\implies F_2 = \frac{9}{4} \ F_1\)

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...
