A uniform metal wire has length 'L', mass 'M' and density ' $Q$ '. It is under tension 'T" and ' $v^{'}$ is the speed of transverse wave along the wire. The area of cross-section of the wire is

Options:

Answer:

Solution:

$(C)$ $V = \frac{T}{m} [m = \frac{M}{L} = \frac{AL ρ}{L} = A ρ]$ $∴ V = \frac{T}{A ρ}$ $∴ V^{2} = \frac{T}{A ρ}$ $A = \frac{T}{V ^{2} ρ}$
