Y is the Young's modulus of the material...

Y is the Young's modulus of the material of a wire of length L and cross-sectional area A. It is stretched through a length l. What is the force constant of the wire?

A

`YA//L`

B

`YA//l`

C

`YL//A`

D

`Yl//A`

Text Solution

Verified by Experts

The correct Answer is:
A
`Y = (FL)/(Al) :. "Force constant" = (F)/(l) = (YA)/(L)`
