Which of the following is not an expression of root mean square velocity ? (A) √3RT/M (B) √3PV/M

Question

Which of the following is not an expression of root mean square velocity ?

(A) \(\sqrt{\frac {3RT}M}\)

(B) \(\sqrt{\frac {3PV}M}\)

(C) \(\sqrt{\frac {3P}D}\)

(D) \(\frac{3PV}{M}\)

Answer 1

Correct option is (D) \(\frac{3PV}{M}\)

\(u = \sqrt{\frac{3RT}M} = \sqrt{\frac {3PV}M} = \sqrt {\frac {3P}D}\)
