Calculate the force of gravity that the Earth (mass 6.0 x 1024 kg) and the Moon (mass 7.4 x 1022 kg) exert on each other. The average Earth-Moon distance is 3.8 x 108 m.
Given the that:
Mass of Earth="6.0 \u00d710^{24}kg"
Mass of Moon="7.4 \u00d710^{22} kg"
The average Earth to Moon distance is = "3.8 \u00d7 10^8 m"
Gravitational constant G= "6.67\u00d710^{-11}Nm^2\/kg^2"
"F=\\frac{Gm_1m_2}{d^2}"
"F= \\frac {6.67\u00d710^{-11}Nm^2\/kg^2\u00d76.0 \u00d710^{24}kg\u00d77.4 \u00d710^{22} kg}{3.8 \u00d7 10^8 m}=20.1\u00d710^{19} N"
Therefore the for between Earth and Moon ="20.1\u00d710^{19}N"
