Which of 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

(a) `Y=("stress")/("strain")=N//m^(2)` or pascal (in SI system)
and `y=("dyne")/(cm^(2))` [in CGS system]
Thus, `Nm^(-1)` is not the unit of Young's modulus.
