Question

A steel wire 100cm long has a mass ok 10 gm. If the wire us under a tension of 400n , what is the speed of transverse waves in the wire

Answer 1

Hii dear,

# Answer- 200 m/s

# Given-

m=10gm=0.01kg

l=100cm=1m

T=400N

v=?

# Formula-

Mass per unit length is calculated by

μ = m/l

μ = 0.01/1

μ = 0.01 kg/m

Tension in the string is given

T = 400N

Velocity of transverse waves through string is given by

v = √(T/μ)

v = √(400/0.01)

v = 200 m/s

Hence, Velocity of transverse waves through string is 200 m/s.

Hope that helped you...
