A stretched wireof length 0.6m is observed to vibrate with a frequency of 30 Hz in the fundamental mode. If the string has a linear massof 0.05 `kg //m`. Find (a) the velocity of propagation of transverse wave in the string (b) the tension in the string.

Text Solution

Verified by Experts

`v= 20 Hz , 1= 0.6m, mu = 0.05 kg m^(-1) ,v= ? , T= ? `
(a) `v= 2vl= 2xx30xx0.6=36 m//s `
`T = v^(2) mu = 36 xx 36 xx0.05 = 64.8 N `
