Assuming the nitrogen molecule is moving with r.m.s. velocity at $\displaystyle 400$ K, the de-Broglie wavelength of nitrogen molecule is close to : (Given : nitrogen molecule weight : $\displaystyle 4.64 \times 10^{-26} \mathrm{~kg}$, Boltzman constant : $\displaystyle 1.38 \times 10^{-23} \mathrm{~J} / \mathrm{K}$, Planck constant : $\displaystyle 6.63 \times 10^{-34} \mathrm{~J} . \mathrm{s}$ )
