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

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

A

`(Y)/(2)`

B

2Y

C

`(3)/(2)Y`

D

Y

Text Solution

Verified by Experts

The correct Answer is:
D
Young's modulus will not be changed by changes in the dimensions.
