In circular orbit of a satellite

Assertion : Orbital velocity of a satellite is greater than its escape velocity. Reason : Orbit of a satellite is within the gravitational field of earth whereas escaping is beyond the gravitational field of earth.

The orbital velocity of an artifical satellite in a circular orbit just above the earth's surface is V_(0) . For a satellite orbiting at an altitude of half of earth's radius, the orbital velocity is

If a satellite is moved from one stable circular orbit to a farther stable circular orbit, then the following quantity increases

Define orbital velocity of a satellite. Derive expressions for the orbital velocity of a satellite. Show that the escape velocity of a body from the earth's surface is sqrt2 times its velocity in a circular orbit just above the earth's surface.
