A space ship of mass $\displaystyle 2 \times 10^4 \mathrm{~kg}$ is launched into a circular orbit close to the earth surface. The additional velocity to be imparted to the space ship in the orbit to overcome the gravitational pull will be (if $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ and radius of earth $\displaystyle =6400 \mathrm{~km}$ ):
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle 8(\sqrt{2}-1) \mathrm{km} / \mathrm{s}$
