The velocities of sound in an ideal gas ...

The velocities of sound in an ideal gas at temperature `T_(1) and T_(2)` K are found to be `V_(1) and V_(2)` respectively. If ther.m.s velocities of the molecules of the same gas at the same temperatures `T_(1) and T_(2)` are `v_(1) and v_(2)` respectively then

A

`v_(2) = v_(1) (V_(1)//V_(2))`

B

`v_(2) =v_(1) (V_(2)//V_(1))`

C

`v_(2) =v_(1)sqrt(V_(2)//V_(1))`

D

`v_(2) =v_(1) sqrt(V_(1)//V_(2))`
