Explain the relation between the gravitational potential energy and the gravitational potential.
1. In terms of potential, we can write the potential energy of the Earth-mass system as, Gravitational potential energy (U) = Gravitational potential (Vr) × mass (m) 2. Thus, gravitational potential is...

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...
