Which units denotes the dimensions ML^2/Q^2

• Measurement

Which of the following units denotes the dimensions ML²/Q², where Q denotes the electric charge?

1. weber (Wb)
2. H/m²
3. Wb/m²
4. henry (H)

Answer

[ML²Q^–2] = [ML²A^–2T^–2]

[Wb] = [ML²T^–2A^–1]

[Wb/m²] = [MT^-2A^-1]

[henry] = [ML²T^–2A^–2]

[H/m²] = [MT^-2A^-2]

So, henry (H) has dimensions ML²/Q²

The correct option is D.
