Imagine a planet whose diameter and mass are both one half of those of earth. The days temperature of this planet
P surface reaches upto \( 800 \mathrm{~K} \). Make calculation and tell whether

W oxygen molecules are possible in the atmosphere of the planet. [Escape velocity from earths surface \( =11.2 \mathrm{~km} / \mathrm{s} \), \( k=1: 38 \times 10^{-23} \mathrm{~J} / \mathrm{K} \), mass of oxygen molecule \( \left.=5.3 \times 10^{-26} \mathrm{~kg}\right] \).
