Satellite Orbit: Determining Altitude

APPHMC-RPAPK4

Geostationary satellites have circular orbits with a 24-hour period that matches the rotation of the Earth. This causes them to remain over the same location on the equator at all times.

Mass of the Earth: $6.0$x${10}^{24}kg$
Radius of the Earth: $6.4$x${10}^{6}m$
Mass of the geostationary satellite: $5.2$x${10}^{2}kg$​

How high above the surface of the Earth is the geostationary satellite?

A

$36$ x ${10}^{6}\text{ }m$

B

$43$ x ${10}^{6}\text{ }m$

C

$278$ x ${10}^{6}\text{ }m$

D

$284$ x ${10}^{6}\text{ }m$

E

The altitude can not be determined from the given information.
