Question
Of the following quantities, which one has dimensions different from the remaining three
Answer: Option D
:
D
Energy per unit volume =[ML2T−2][L3]=[ML−1T−2]
Force per unit area =[MLT−2][L2]=[ML−1T−2]
Product of voltage and charge per unit volume
=V×QVolume=VltVolume=Power×TimeVolume
⇒[ML2T−3][T][L3]=[ML−1T−2]
Angular momentum per unit mass =[ML2T−1][M]=[L2T−1]
So angular momentum per unit mass has different dimension.
