Question

A string of linear density 0.4 kg / m is stretched with force of 1000 N. A transverse wave is set up along it. The speed of the wave is (A) 75 m/s (B) 25 m/s (C) 100 m/s (D) 50 m/s

v =√(T/μ) =√(1000/0.4) =50 ms -1

Q. A string of linear density $0.4 k g / m$ is stretched with force of $1000 N$ . A transverse wave is set up along it. The speed of the wave is

75 m/s

25 m/s

100 m/s

50 m/s

$v = \frac{T}{μ}$
$= \frac{1000}{0.4}$
$= 50 m s^{- 1}$
