A sound wave of frequency 440 Hz is passing through air. An `O_2` molecule (mass`=5.3xx10^(-26)Kg)` is set in oscillation with an amplitude of `10^-6m` speed at the centre of its oscillation is :

A

`1.70xx10^-5m//s`

B

`17.0xx10^-5m//s`

C

`2.76xx10^-5m//s`

D

`2.77xx10^-5m//s`

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(max)=omega_nA`
`=(2pif)A=(2pi)(440)(10^-6)`
`=2.76xx10^-5m//s`
