Okay, so the question seems really simple so I don't know what I'm missing
A satellite orbits at a fixed point above the Earth's equator. Assuming the earth has uniform
density, radius R, and angular frequency of rotation, omega
Find an expression for eta, such that the orbital radius of the satellite is expressed as eta R
The Attempt at a Solution
Centripetal force= gravitational force
But I honestly have no idea how to incorporate the Eaths radius. Every time I try it cancels.
Thanks in advance :)
