Question

The Young's modulus of the material of the wire of length $L$ and radius $r$ is $YN/m^2$. If the length is reduced to $L/2$ and radius $r/2$, the Young's modulus will be:

• A. $\frac{Y}{2}$
• B. $Y$
• C. $2Y$
• D. $4Y$

Answer 1

The correct option is B $Y$

Young's modulus depends upon the nature of the material and is independent of the dimensions of the material.
