Question

The moon has a mass of 7.348 X 10^{22} kg and is 384.4 X 10^{5} km from the Earth, which has a mass of 5.972 X 10^{24 }kg. Solve for the force of gravity between the Earth and Moon. (ans: 1.98 X 10^{16} N) Show work.

Step 1

Let m_{m} be the mass of moon, m_{e} be the mass of earth, r be the distance between earth and moon, and G be the gravitational constant.

Write the given values of question.

Step 2

Write the expression for the gravitational force betwe...
