1. The problem statement, all variables and given/known data 2. Relevant equations fg=Gm1m2/r^2 3. The attempt at a solution Let FgE be the force of gravity of Earth, and FgM be force of gravity of the moon. We need a net gravitational force of 0 N. So: FgE-FgM=0 FgE=FgM Can someone attempt to solve this and see if the answer matches the book answer which is 3.8 x 10^7. I have tried this with many different methods, and the closest I got was 4.2 x 10^7. So if someone gets the same answer as me or the book, can you please reply.
