The Young's modulus of a wire Y. If the energy per unit volume is E, then the strain will be

A

`sqrt((2E)/(Y))`

B

`Esqrt(2Y)`

C

EY

D

`(E)/(Y)`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Energy per unit volume `=(1)/(2)xxYxx("strain")^(2)`
`therefore "Strain" =sqrt((2E)/(Y))`
