Question

what is escape velocity ? write the expression of escape velocity . Also calculate the numerical value of escape velocity?​

Answer 1

escape velocity is a minimum velocity by which an object should be thrown that it escapes from the Earth's orbit

$v = \sqrt{2gr}$

v=11200m/s

pls mark the brainliest

Answer 2

Explanation:

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
