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:
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.
