MCQ

The unit of Young’s modulus is

A
$N{m^2}$
✓
$N{m^{ - 2}}$
C
$Nm$
D
$N{m^{ - 1}}$

✓

Answer

Correct option: B.

$N{m^{ - 2}}$

b
The Young's modulus is given as;

$Y =\frac{\text { Stress }}{\text { Strain }}$

The unit of Young's modulus is same as that of the stress because the strain a dimensionless quantity.

So, unit of Young's modulus is same as stress i.e. $N / m ^2$.
