The young's modulus of a wire of length ...

The young's modulus of a wire of length (L) and radius (r ) is Y. If the length is reduced to` L/2` and radius `r/2` , then its young's modulus will be

A

Y

B

2Y

C

`(Y)/(4)`

D

`(Y)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Young's modulus is property of material. So, it is independent of the length.
