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

1. Energy per unit volume
2. Force per unit area
3. Product of voltage and charge per unit volume
4. Angular momentum

Correct answer: Angular momentum

Solution

Energy per unit volume, force per unit area, and the product of voltage and charge per unit volume all have the same dimensions of energy density ([ML⁻¹T⁻²]). However, angular momentum has dimensions of [ML²T⁻¹], which is different.
