A satellite revolves in elliptical orbit around a planet of mass `M`. Its time period is `T` and `M` is at the centre of the path. The length of the major axis of the path is: (neglect the gravitational effect of other object in space)

A satellite of mass m revolves in a circular orbit of radius R a round a planet of mass M. Its total energy E is :-

A satellite revolves around the earth along a circular path. If the mass of the satellite is 1000 kg and its distance from the centre of the earth is 20000 km, find the magnitude of the earth's gravitational force acting on the satellite.
