Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason RAssertion A: If the average kinetic energy of $\displaystyle \mathrm{H}_2$ and $\displaystyle \mathrm{O}_2$ molecules, kept in two different sized containers are same, then their temperatures will be same.Reason R: The r.m.s. speed of $\displaystyle \mathrm{H}_2$ and $\displaystyle \mathrm{O}_2$ molecules are same at same temperature.Choose the correct answer from the options given below
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle \mathbf{A}$ is true but $\displaystyle \mathbf{R}$ is false
