Which one the following is not a unit of Young's modulus ?

A

`Nm^(-1)`

B

`Nm^(-2)`

C

`"dyne" cm^(-2)`

D

mega pascal

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `y=("Stress")/("Strain")=N//m^(2)` or pascal (in Sl system)
and `y=("dyne")/(cm^(2))" "` (in CGS System)
Thus, `Nm^(-1)` is not the unit of Young's modulus.
