Answer:
[tex]F=8.45\times 10^{-8}\ N[/tex]
Explanation:
Given that,
Mass of a boy is 78 kg
Mass of a girl is 65 kg
We need to find the force of gravitational attraction between them if they are 2 m away.
The formula for the gravitational force is given by :
[tex]F=\dfrac{Gm_1m_2}{r^2}\\\\F=\dfrac{6.67\times 10^{-11}\times 78\times 65}{(2)^2}\\\\=8.45\times 10^{-8}\ N[/tex]
So, the force between them is [tex]8.45\times 10^{-8}\ N[/tex].
