At a given temperature, ratio of root mean square velocities of two different gases of molecular weights `M_(1) and M_(2)` respectively is

A

`sqrt(M_1/M_2)`

B

`sqrt(M_2/M_1)`

C

`sqrt((M_1+M_2)/(M_1-M_2))`

D

`sqrt((M_1-M_2)/(M_1+M_2))`

Text Solution

Verified by Experts

The correct Answer is:
B
Since `v_(rms)=sqrt((3RT)/(M)) implies (v_1)/(v_2)=sqrt((M_2)/(M_1))`.
