A metallic wire of 1 m length has a mass of `10xx10^(-3)`kg. If a tension of 100 N is applied to a wire, what is the speed of transverse wave ?

Options

A. `100 ms^(-1)`
B. `10 ms^(-1)`
C. `200 ms^(-1)`
D. `0.1 ms^(-1)`

Answer

A

Explanation

Linear density `m = ("mass")/("length") = (10 xx 10^(-3))/(1) =10 xx 10^(-3) kg//m`
The speed of the transverse wave is `V = sqrt((T)/(m)) = sqrt((100)/(10 xx 10^(3))) = 100 m//s`
