The Young's modulus of steel wire of radius $r$ and length $L$ is $Y$. If the radius $r$ and length $L$ of the wire are doubled then the value of $Y$
Answer: (C) remains unchanged
Young's modulus is a property of the material. Changing the wire's size changes how much it stretches for a given load, but not $Y$.
