Q. 34.3( 7 Votes )

A steel wir

Answer :


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)


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
