1. The problem statement, all variables and given/known data A satellite is in a circular orbit 655km above Earth's surface. Determine the magnitude of the gravitational acceleration at this height. 2. Relevant equations Eg=mgh Eg=-GMm/r 3. The attempt at a solution Would I just set the aforementioned eqations equal to each other and re-arrange to solve for g? I would also have to solve for the change in Eg, as well, right?
