Which of the following physical quantities has different dimensional f

1.	Which of the following physical quantities has different dimensional formula ?
Answer» Energy per unit volume Product of voltage and CHARGE per unitvolume. Force acting per unit area Angular momentum Solution :Energy per unit volume `("energy")/("volume")=(E)/(V)` `=(M^(1)L^(2)T^(-2))/(L^(3))=M^(1)L^(-1)T^(-2)` (B) Products of voltage and charge per unit volume `="Voltage" xx("Charge")/("Volume")` `=(VxxQ)/("Volume")` `=(M^(1)L^(2)T^(-2))/(L^(3))` (c) Force acting per unit area. `(F)/(A)=(M^(1)L^(1)T^(-2))/(L^(2))` `=M^(1)L^(-1)T^(-2)` (d) Angular momentum `=MVR` `=M^(1)L^(1)T^(-1)XXL^(-1)` Hence D is correct option.
