A uniform metal wire has length ' $L$ ', mass ' $M$ ' and cross-sectional area ' $A$ '. It is under tension ' $T$ ' and ' $V$ ' is the speed of transverse wave along the wire. The density of the wire

Options:

Answer:

Solution:

For transverse waves on a wire $V = \frac{T}{m}$ The mass per unit length can be written as $m = \frac{M}{L} = \frac{A L ρ}{L} = A ρ$ $∴ V = \frac{T}{m} = \frac{T}{A ρ} ∴ V^{2} = \frac{T}{A ρ} ∴ A = \frac{T}{V ^{2} ρ}$
