A satellite orbits the earth at a height of 200 KM in a cirlce of radius 6570 km. Find the speed of the satellite and the time taken tocomplete one revolution. Assume teh earth's mass is 6.0 X 10 exp 24.(adsbygoogle = window.adsbygoogle || []).push({});

(Hint: The gravitation force provides the centripetal force)

i found Velocity using:

v = square root of gravity constant * m central / r

but they want the time, what can i use

thanks
