A wire of density 
is stretched between two clamps 1 m apart and is subjected to an extension of 
. The lowest frequency of transverse vibration in the wire is 
)
Text Solution
Verified by ExpertsThe correct answer is:
B
For wire if
M = mass, ρ ρ = density, A = Area of cross section
V = volume, l = length, Δ Δ l = change in length
Then mass per unit length 
And Young’s modules of elasticity 
⇒ ⇒ 
. Hence lowest frequency of vibration 
⇒ ⇒
