At what temperature will the rms speed of oxygen molecules become just sufficient for escaping from the Earth's atmosphere? (Given : Mass of oxygen molecules (m) \(=2.76 \times 10^{-26} \mathrm{~kg}\), Boltzmann's constant \(\mathrm{k}_{\mathrm{B}}=1.3 \mathrm{~B} \times 10^{-23} \mathrm{~J} \mathrm{~K}^{-1}\))
- \(5.016 \times 10^{4} \mathrm{~K}\)
- \(1.254 \times 10^{4} \mathrm{~K}\)
- \(0.360 \times 10^{4} \mathrm{~K}\)
- \(2.50 \mathrm{E} \times 10^{4} \mathrm{~K}\)
Answer
(B) 1.254 10^ 4 ~K
