MCQ
The units of modulus of rigidity are
  • A
    $N - m$
  • B
    $N/m$
  • C
    $N - {m^2}$
  • $N/{m^2}$

Answer

Correct option: D.
$N/{m^2}$
d
We know that the modulus of rigidity is defined as:

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

Since strain is a dimensionless quantity. So its unit will be same as that of stress.
