Question

A 5.5 m long string has a mass of 0.035 kg . If the tension in the string is 77 N , the speed of a wave on the string is (A) 110 ms- 1 (B) 165 ms- 1 (C) 77 ms- 1 (D) 102 ms- 1

μ =(0.035/5.5)kgm- 1, T=77N Velocity of transverse wave along string v=√(T/μ )=√(77 × 5.5/0.035)=110ms- 1

Q. A $5.5 m$ long string has a mass of $0.035 k g$ . If the tension in the string is $77 N$ , the speed of a wave on the string is

$110 m s^{- 1}$

$165 m s^{- 1}$

$77 m s^{- 1}$

$102 m s^{- 1}$

$μ$ $= \frac{0.035}{5.5} k g m^{- 1}, T = 77 N$
Velocity of transverse wave along string
$v = \frac{T}{μ} = \frac{77 \times 5.5}{0.035} = 110 m s^{- 1}$
