Young's modulus of the material of a wire of length $L$ and cross-sectional area $A$ is $Y$. If the length of the wire is doubled and the cross-sectional area is halved, then Young's modulus will be:
Answer: (C) $Y$
Young's modulus is a property of the material only. Changing the length or area of the wire does not change it, so it remains $Y$.
