1. Homework Statement
The radius of the Earth is 6.86 e6 m and the mass of the earth is 5.98 e24kg. There is a satellite floating in space at a point where the earth's gravitational acceleration is 3.2 m/s^2.

How far above the Earths surface is the Satellite?
2. Homework Equations
GMm/R^2 = F


3. The Attempt at a Solution
So I did 3.2 = GM/R^2....R = 1164480.51. But that isn't right - could someone please guide me as to how I should go about setting up the equation

That is the correct equation. Why do you think your answer is wrong?

I didn't check the calculation, but let's assume you did it correctly and R is indeed 1164480.

Then whát distance exactly is 1164480 (and in what units? Always state your units!).
Is that the distance you were asked to find?
