Three closed vessels A, B and C are at the same temperature T and contain gases. Vessel A contains only `O_(2)`, B contains only `N_(2)` and C contains a mixture of equal quantities of `O_(2)` and `N_(2)`. If the rms speed of `O_(2)` molecules in vessel A is `v_(1)` and that of `N_(2)` molecules in vessel B is `v_(2)` then the rms speed of `O_(2)` molecules in vessel C is

Options

A. `(V_(1)+V_(2))/(2)`
B. `V_(1)`
C. `sqrt(4v_(2))`
D. `sqrt(3kT//m)`

Answer
