A unifrom wire of length 1 m has mass 1 g . Under the tension 40 N . Find the velocity of sound wave ( transverse ) in the wire .

Text Solution

Verified by Experts

Tension , `T=40 N `
mass per unit length
` m=(1 g)/(1m) =( 10 ^(-3) Kg)/( 1m) =10 ^(-3) Kg* m^(-1)`
`therefore ` velocity of transverse wave ,
`V=sqrt((T)/(m))= sqrt((40 )/(10^(-3))=200 m * s^(-1)`
