A transverse wave in propagating on a stretched string of mass per unit length 32 g/m. The tension on the string is 80 N. The speed of the wave over the string is

A

`5//2 m//s`

B

`sqrt(5//2) m//s`

C

`2//5 m//s`

D

`sqrt(2//5) m//s`

Text Solution

Verified by Experts

The correct Answer is:
C
Speed of wave in a string
`v=sqrt(T)/(mu)`
given T=80 N
`=32xx10^(-3) kg//m`
`=100xx1/2`
`=50 m//s`
