# Which of the following statements regarding dimensions is correct?

The dimension of any physical quantity includes the power fundamental physical quantities.

##### SOLUTION
Dimensional formula includes power of fundamental quantites.
For example ; Unit of force is [$M^1L^1T^{-2}$]
Radian is not a fundamental physical quantity it comes under supplementary units.
Dimension of work is $[M^1 L^2 T^{-2}]$ whereas rate of doing work is  $[M^1 L^2 T^{-3}]$
