Question

Calculate the gravitation force between a object of mass 80 kg and a object of mass 1200 kg kept at a distance of 10 m.

Answer 1

$m_1=80kg$

$m_2=1200kg$

$r=10m$

$F=\frac{G{m}_1{m}_2}{r^2}$

$F=\frac{(6.67\times {10}^{-11})\left(80\right)\left(1200\right)}{{\left(10\right)}^2}$

$F=6.40\times {10}^{-8}N$
