Question

i) Define escape velocity of the body and critical velocity
of a satellite​

Answer 1

Answer:

Hence it can be neglected. Therefore the critical velocity of the satellite orbiting very close to the earth's surface. Thus the escape velocity of a body from the surface of the planet (earth) is √2 times the critical velocity of the body when it is orbiting close to the planet's (earth's) surface.

Answer 2

Answer:1. escape velocity is the velocity ,of given to the body then it escape  the gravitational poll of the earth

2.Critical Velocity of Satellite. The constant horizontal velocity given to the satellite so as to put it into stable circular orbit around the earth is called as critical velocity and is denoted by Vc.
