Kinetic Theory — Easy JEE physics MCQ

The ratio of rms speeds of $O_2$ and $H_2$ at the same temperature is:
  1. A. $1:4$
  2. B. $4:1$
  3. C. $1:2$
  4. D. $2:1$

Solution

$v_{rms} = \sqrt{\frac{3RT}{M}}$ $\frac{v_{O_2}}{v_{H_2}} = \sqrt{\frac{M_{H_2}}{M_{O_2}}} = \sqrt{\frac{2}{32}} = \frac{1}{4}$
