Question 1 of 5

A wire of length L, area of cross section A is hanging from a fixed support. The length of the wire changes to $true$ when mass M is suspended from its free end. The expression for Young’s modulus is :

$\frac{\mathrm{M} g L}{\mathrm{~A}\left(\mathrm{~L}_{1}-\mathrm{L}\right)}$

$\frac{\mathrm{Mg}\left(\mathrm{L}_{1}-\mathrm{L}\right)}{\mathrm{AL}}$

$\frac{\mathrm{M} g \mathrm{~L}_{1}}{\mathrm{AL}}$

$\frac{\mathrm{Mg} L}{\mathrm{AL}_{1}}$
