Satellite & Planetary Motion|Escape Velocity

If v_(0) be the orbital velocity of an articial satellite orbital velocity of the same satellite orbiting at an altitude equal to earth's radius is

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.

Gas escapes from the surface of a planet because it acquires an escape velocity. The escape velocity will depend on which of the following factors: (1) Mass of the planet (2) Radius of the planet (3) Mass of the particle escaping (4) Temperature of the planet

Assertion: Two different planets have same escape velocity. Reason: Value of escape velocity is a universal constant.
