The force of attraction (A) between two objects, whose masses are fixed, varies inversely with the square of their distance of separation 9d). The force of attraction between them is 2 units when the distance is 5 cm. what is the distance between the two objects, if the attraction between them is 8 units?

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...
