MHT CET 2022 11th August Evening Shift | Heat and Thermodynamics Question 75 | Physics

Two monatomic ideal gases A and B of molecular masses '$$m_1$$' and '$$m_2$$' respectively are enclosed in separate containers kept at the same temperature. The ratio of the speed of sound in gas A to that in gas B is given by

$$\sqrt{\frac{\mathrm{m}_2}{\mathrm{~m}_1}}$$

$$\frac{\mathrm{m}_1}{\mathrm{~m}_2}$$

$$\sqrt{\frac{\mathrm{m}_1}{\mathrm{~m}_2}}$$
