## Homework Statement

A satellite is in a circular orbit 655km above Earth's surface. Determine the magnitude of the gravitational acceleration at this height.

## Homework Equations

Eg=mgh

Eg=-GMm/r

## 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?
