A remote - sensing satellite of earth revolves in a circular orbit at a height of $\displaystyle 0.25 \times 10^6 \mathrm{~m}$ above the surface of earth. If earth's radius is $\displaystyle 6.38 \times 10^6 \mathrm{~m}$ and $\displaystyle \mathrm{g}=9.8 \mathrm{~ms}^{-2}$, then the orbital speed of the satellite is :
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle 7.76 \mathrm{~km} \mathrm{~s}^{-1}$
