Two monatomic ideal gases 1 and 2 of molecular masses m₁ and m₂, respectively are enclosed in separate containers kept at same temperature. The ratio of the speed of sound in gas 1 to that in gas 2 is given by

• A

  $\sqrt{\left({\mathrm{m}}_1/{\mathrm{m}}_2\right)}$

• B

  $\sqrt{\left({\mathrm{m}}_2/{\mathrm{m}}_1\right)}$

• C

  ${\mathrm{m}}_1/{\mathrm{m}}_2$

• D

  ${\mathrm{m}}_2/{\mathrm{m}}_1$
