  • A U = (kM)\(\frac{1}{2}\)
  • B U = (kM)2
  • C U = \(\sqrt{\frac{k}{m}}\)
  • D U = \(\frac{k}{m}\)
Correct Answer: Option C
Explanation:
The relationship between (U) of a gas molecule and the relative molecular mass is \(\bar{U}\) = (\(\frac{k}{m}\))\(^{\frac{1}{2}}\)
or \(\bar{U}\) = \(\sqrt{\frac{k}{m}}\)
