NEET Physics Kinetic Theory of Gases Questions Solved

A cubical box with porous walls containing an equal number of O2 and H2 molecules is placed in a large evacuated chamber. The entire system is maintained at constant temperature T. The ratio of vrms of O2 molecules to that of the vrms of H2 molecules, found in the chamber outside the box after a short interval is

1.  122                             

2.  14

3.  12
