What is the escape velocity of a body?

Solution
The minimum velocity with which a body must be projected such that it escapes from the earth's gravitational pull is called escape velocity.
More generally, escape velocity is the speed at which the sum of an object's kinetic energy and its gravitational potential energy is equal to zero. An object which has achieved escape velocity is neither on the surface nor in a closed orbit (of any radius).
