At what temperature will the rms speed of oxygen molecules become just sufficient for escaping from the Earth's atmosphere ?
(Given :
Mass of oxygen molecule $\displaystyle (\mathrm{m})=2.76 \times 10^{-26} \mathrm{~kg}$
Boltzmann's constant $\displaystyle \mathrm{k}_{\mathrm{B}}=1.38 \times 10^{-23} \mathrm{~J} \mathrm{~K}^{-1}$ )
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle 8.360 \times 10^4 \mathrm{~K}$
