A) \[200m{{s}^{-1}}\]
B) \[100m{{s}^{-1}}\]
C) \[0.1m\text{ }{{s}^{-1}}\]
D) \[10m\text{ }{{s}^{-1}}\]
Correct Answer: B
Solution :
: Here, Mass per unit length of the wire, \[\mu =\frac{10\times {{10}^{-3}}kg}{1m}=10\times {{10}^{-3}}kg\,\,{{m}^{-1}}\] Tension, \[T=100\text{ }N\] The speed of transverse wave on the wire is \[v=\sqrt{\frac{T}{\mu }}=\sqrt{\frac{100N}{10\times {{10}^{-3}}kg\,{{m}^{-1}}}}=100m\,{{s}^{-1}}\]
