Three closed vessels `A,B`, and `C` are at the same temperature `T` and contain gases which obey the Maxwell distribution of speed. Vessel `A` contains only `O_(2),B` only `N_(2)` and `C` a mixture of equal quantities of `O_(2)` and `N_(2)`. If the average speed of `O_(2)` molecules in vessel `A` is `V_(1)`, that of the `N_(2)` molecules in vessel `B` is `V_(2)`, the average speed of the `O_(2)` molecules in vessel `C` will be:

Options

A. `(v_(1) + v_(2))//2`
B. `v_(1)`
C. `(v_(1)v_(2))^(1//2)`
D. `sqrt(3kT//M)`

Answer

B
