Question

A body is orbiting very close to the earth’s surface with kinetic energy KE. The energy required to completely escape from it is

$K E$
$2 K E$
$\frac{K E}{2}$
$\frac{3 K E}{2}$

Hint:

Hence the answer is KE

The correct answer is: $K E$

The energy given to the body so as to completely escape from its orbit is equal to its kinetic energy KE
