Molecular Speeds & Maxwell Distribution

If $m$ ' represents the mass of each molecules of a gas and $T$ ' its absolute temperature then the root mean square speed of the gas molecule is proportional to

Show answer and solution

Answer: (a)

$v_{rms} = \sqrt{\frac{3kT}{m}}$
$v_{rms} \propto m^{-1/2}T^{1/2}$
So the answer is (a).
