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 \(F = \frac{G \ m_1m_2}{r^2}\) \(\frac{F_2}{F_1} = \left(\frac{r_1}{r_2}\right)^2\) \(\frac{F_2}{F_1} = \left(\frac{r_1}{\frac{2}{3}r_1}\right)^2\) \(\frac{F_2}{F_1} = \frac{9}{4}\) \(\implies F_2 = \frac{9}{4} \ F_1\)
