Question

The young's modulus of a wire of length $L$ and radius $r$ is $Y$ $N/m^{2}$. If the length and radius are reduced to $L/2$ and $r/2$, then its young's modulus will be

• A. Y/2
• B. Y
• C. 2Y
• D. 4Y

Answer 1

Answer: (B)

Y

Answer 2

Young's modulus does not depend on the length or radius of the material.
