Re: Law of Universal Gravitation
The anglular velocity of the satellite must be same as the angular velocity of the spin of the earth. Let the mass of the satellite be m and the mass of the earth be M and the angular velocity of earth be w (w = 2*pi/24 hours). The force balance eqn

mrw^2 = GMm/r^2

Solving you get r = (GM/w^2)^(1/3)
