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
