You are sitting next to your friend on ground. Is there any gravitational force of attraction between you two?
1. Yes, there exists a gravitational force between me and my friend sitting beside each other. 2. The gravitational force between any two objects is given by, \(\vec{F} = G\frac{m_1\,m_2}{r^2}\) Where, G = universal gravitational...

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