Escape velocity on the earth’s surface is ________ .

Solution:

The minimum velocity of the body that should be given to the body to enable it to escape away from the earth’s gravitational field is called escape velocity.
Its value on the earth’s surface is 11.2 km/s.
Escape velocity is $2^{1/2}$ times the orbital velocity i.e. $V_e$ = $2^{1/2} V_o$ .
Escape velocity from the Sun = 614 km/s
Escape velocity from the moon = 2.4 km/s
