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.
