What is the average force of gravity between Earth and the moon?

[snakeboy91]

Show that the average force of gravity between Earth (mass = 6.0 X 10^24kg) and the moon (mass = 7.4X10^22 kg) is 2.1X10^20 N. The average earth-moon distance is 3.8 X 10^8 m

Hi snakeboy, and welcome to PF.

The forum rules require you to show your work before we can help. You are also supposed to use the three headings that appear when you try to post in this section.

Are you not aware that $F= GmM/r^2$?
