Equation for Satellite in geosynchronous oribt

[emerica1254]

Homework Statement

Find Velocity of satellite in GS orbit around Earth but you cannot use r in the solution

And find r of satellite in GS orbit but you cannot use velocity in the solution

Homework Equations

V=Sqroot of G*Me/r, Me being the mass of the Earth but you can't use r from this equation

The Attempt at a Solution

I know at GS the satellite would travel around the Earth in 24 hours and a full revolution around a circle is 2pi, so i can get the angular revolution but then i can't figure out v without using r still

The velocity depends on the radius r. I am not sure how they want you to answer the first part.

As for the second part, you can get out easily by using the centripetal force =mω²r
