Young's modules of material of a wire of length '$L$' and cross-sectional area $A$ is $Y$. If the length of the wire is doubled and cross-sectional area is halved then Young's modules will be :
Solution
<p>Young's modulus depends on the material not length and cross sectional area. So young's modulus remains same.</p>
