**bobpursley**, Monday, February 22, 2010 at 11:11amNewton has a neat law of gravity:

Fg= G Me Ms /distance^2

That leads to the inverse relation.

The weight at Earth's surface is mg, which is at one Earth radii.

So if you go one more Earth radii, the weight will be mg/2^2

and if you go one more, as you asked, the weight will be mg/3^2
