the maximum pressure variation that the human ear can tolerate in loud sound is about `30 N //m^(2) ` . The corresponding maximum displacement for a sound wave ina air having a frequency of ` 10^(3) Hz`is
take velocity of sound in air as 300 m/s and density of air ` 1.5 kg // m ^(3)`
A. `(2pi)/3 xx10^(-2)m`
B. `(2 xx10 ^(-4))/pi m`
C. `(pi)/3 xx10^(-2)m`
D. `(10 ^(-4))/(3pi) m`
