The escape velocity of a body on the earth surface is $$11.2 \mathrm{~km} / \mathrm{s}$$. If the same body is projected upward with velocity $$22.4 \mathrm{~km} / \mathrm{s}$$, the velocity of this body at infinite distance from the centre of the earth will be:

$$11.2 \sqrt{2} \mathrm{~km} / \mathrm{s}$$

Zero

$$11.2 \mathrm{~km} / \mathrm{s}$$

$$11.2 \sqrt{3} \mathrm{~km} / \mathrm{s}$$
