N molecules, each of mass m, of gas A and 2 N molecules, each of mass 2 m, of gas B are contained in the same vessel which maintained at a temperature T. the mean square of he velocity of molecules of B type is denoted by v² and the mean square of the X component of the velocity of A type is denoted by ω², then $\left(\dfrac{\omega^2}{v^2}\right)$ is
