1. The problem statement, all variables and given/known data At what height above the earth's surface is the acceleration due to gravity 10% of that at sea level? 2. Relevant equations F= Gm1m2/r(squared) 3. The attempt at a solution I think some how one of the masses is moved over so that F/m=a and I think .10 is multiplied times something like (r squared) or (r + x)squared.
