Find wave speed in a string of length 7m, mass 0.035 kg and having a t

1.	Find wave speed in a string of length 7m, mass 0.035 kg and having a tension of 60.5 N.
Answer» (A) 77 m/s` (B) 102 m/s` (C) 110 m/s (D) 165 m/s` SOLUTION :We have, `V = sqrt ((T)/(mu)) = sqrt((T)/( M //L )) = sqrt((TL )/(M))` `therefore v = sqrt (( 60.5 xx7 )/(0.035)) =110 (m)/(s)`
