The mass of the earth is \(6 \times 10^{24}\ kg\) and that of the moon is \(7.4 \times 10^{22}\ kg\). If the distance between the earth and the moon is \(3.84 \times 10^5\ km\). Calculate the force exerted by the earth on the moon. \(G\ =\ 6.7 \times 10^{–11}\ Nm^{2} kg^{-2}\).

According to the universal law of gravitation, the force of attraction between two bodies is,

\(F\ =\ \frac{Gr^2}{m_1 \times m_2}\)
\(F\ =\ \frac{Gm_2}{m_1 \times r^2}\)
\(F\ =\ \frac{Gm_1}{m_2 \times r^2}\)
\(F\ =\ \frac{Gm_1m_2}{r^2}\)

Force exerted by the earth on the moon (\(F\)) \(=\) \(\times 10^{20}\ N\)

(Note: Enter your answer with three decimal digits)
