GPS (Global Positioning System) satellites orbit at an altitude of 2.0×10^7 m.
Find the orbital period.(hours)I use the equation T=(2pi/sqrt(GM))r^(3/2).
Shouldnt that be the correct way of doing it? I know I am supposed to add the altitude to the radius of the earth, G is known, M of Earth is known. I just don't understand where I am going wrong with this. It should be a simple problem yet I am not able to get the correct answer. is it possible I am doing something as silly as not converting something somewhere?
If anyone could offer some help, it would be greatly appreciated.
