D

$3{E_k}$

A satellite with kinetic energy ${E_k}$ is revolving round the earth in a circular orbit. How much more kinetic energy should be given to it so that it may just escape into outer space

Binding energy = $-$ kinetic energy
And if this amount of energy $({E_k})$ given to satellite then it will escape into outer space
