Question

derive equation of orbital velocity and energy of satellite​

Answer 1

Answer:

Suppose M and R are the mass and radius of the Earth respectively, then r = R + h. To revolve the satellite, a centripetal force of \frac{mv_{o}^2}{r} is needed which is provided by the gravitational force G\frac{Mm}{r^2} between the satellite and the Earth. But GM = gR^2, where g is the acceleration due to gravity.
