Question

Select One Correct Option from the following:Three closed vessels A, B and C are at the same temperature T and contain gases which obey the Maxwellian distribution of velocities. Vessel A contains only $O_2$, B only $N_2$, and C a mixture of equal quantities of O2 and N2. If the average speed of the $O_2$molecules in vessel A is $\upsilon_1$, that of $N_2$ molecules in vessel B is $\upsilon_2$, the average speed of the $O_2$ molecules in vessel C is [M is the mass of an $O_2$ molecule.
(A) $\frac{\upsilon_1+\upsilon_2}{2}$
(B) $\upsilon_1$
(C) $\sqrt{\upsilon_1 \upsilon_2}$
(D) $\sqrt{3kT/M}$
