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

Options

A. Energy density
B. Force per unit area
C. Product of charge per unit volume and voltage
D. Angular momentum per unit mass

Answer

D

Explanation

Energy densit `=("Energy")/("volume")=ML^(-1)T^(-2)=F/A=("charge")/("volume")xx("work")/("charge")=ML^(-1)T^(-2)`
`(ML^(2)T^(-1))/M=M^(@)L^(2)T^(-1)` (different)
