Find wave speed in a string of length 7m, mass `0.035 kg` and having a tension of `60.5 N.`

A

(A) 77 m/s`

B

(B) 102 m/s`

C

(C) 110 m/s

D

(D) 165 m/s`

Text Solution

Verified by Experts

The correct Answer is:
C
We have, `v = sqrt ((T)/(mu)) = sqrt((T)/( M //L )) = sqrt((TL )/(M))`
`therefore v = sqrt (( 60.5 xx7 )/(0.035)) =110 (m)/(s)`
