Chapter 5: Problem 74
Challenge Problem Gravitational Force According to Newton's Law of Universal Gravitation, the attractive force \(F\) between two bodies is given by $$F=G \frac{m_{1} m_{2}}{r^{2}}$$ where \(m_{1}, m_{2}=\) the masses of the two bodies \(r=\) distance between the two bodies \(G=\) gravitational constant \(=6.6742 \times 10^{-11}\) newtons " meter \(^{2}\). kilogram \(^{-2}\) Suppose an object is traveling directly from Earth to the moon. The mass of Earth is \(5.9742 \times 10^{24}\) kilograms, the mass of the moon is \(7.349 \times 10^{22}\) kilograms, and the mean distance from Earth to the moon is 384,400 kilometers. For an object between Earth and the moon, how far from Earth is the force on the object due to the moon greater than the force on the object due to Earth?
