What is the relation between escape and orbital velocity?

What is the relation between orbital and escape velocity ?

Obtain the relation between escape velocity and critical velocity when satellite is orbiting very close to earth. OR Show//prove that the escape velocity of a satellite orbiting round the earth is equal to sqrt2 time its critical velocity. OR Show that V_e = sqrt2. V_c for a satellite orbiting round the earth.

The graph that represents the relation between orbital velocity (v_(0)) of a satellite and radius (r) of the orbit around earth is

What is the relation between drift velocity and electric current?

Let a planet revolving close to the earth, Obtain relation between escape speed and orbital speed.

Define orbital velocity. Obtain the relation between orbital velocity and acceleration due to gravity g, for a satellite orbiting very close to the surface of the earth.
