$A$ gas molecule of mass $M$ at the surface of the Earth has kinetic energy equivalent to $0\,^{\circ}C$. If it were to go up straight without colliding with any other molecules,how high would it rise? Assume that the height attained is much less than the radius of the Earth. ($k_B$ is Boltzmann constant)
- A$0$
- B$\frac{273 k_B}{2Mg}$
- C$\frac{546 k_B}{3Mg}$
- D$\frac{819 k_B}{2Mg}$
