# Of the following quantities which one has the dimensions different from the remaining three?

Angular momentum per unit mass

##### SOLUTION
Energy density $=\dfrac{energy}{volume}=\dfrac{ML^{2}T^{-2}}{L^{3}}=ML^{-1}T^{-2}$
Force per unit area $=\dfrac{MLT^{-2}}{L^{2}}=ML^{-1}T^{-2}$
Product of the charge per unit volume and voltage $=Q\dfrac{\left ( IT \right )V}{Volume}=\dfrac{ML^{2}T^{-2}}{L^{3}}=ML^{-1}T^{-2}$
Angular momentum per unit mass
$=\dfrac{M^{1}L^{2}T^{-1}}{M}$$=L^{2}T^{-1}$
So, option D is correct.
