Which one of the following is not a unit of Young's modulus ?
Updated On: Aug 1, 2022
- $Nm^{-1}$
- $Nm^{-2}$
- dyne $cm^{-2}$
- Mega Pascal
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$y=\frac{\text { stress }}{\text { strain }}= N / m ^{2}$ or pascal (in SI system)
and $y=\frac{\text { dyne }}{ cm ^{2}}$ (in CGS. system)
Thus, $Nm ^{-1}$ is not the unit of Young's modulus
