Q. 34.3( 7 Votes )

A steel wir

Answer :

Given:

Mass of the steel wire, M = 2.10 Kg


Length of the string, L = 12 m


Mass per unit length, m = M/L


m = 2.10 Kg/ 12m


m = 0.175 Kgm-1


Velocity of the transverse wave, V = 343ms-1


The Tension, T in transverse wave in the string is given by,


T = V2m …(1)


Where,


T = tension in the string


m = mass per unit length


V = velocity of wave


By putting the given data in equation (1), we get,


T = (343ms-1)2× 0.175Kgm-1


T = 20588.5 N
