Which of the following units denotes the dimensions `ML^(2)//Q^(2)`, where Q denotes the electric charge ?

Options

A. weber (Wb)
B. `Wb//m^(2)`
C. henry(H)
D. `H//m^(2)`

Answer

C

Explanation

`[ML^(2)Q^(-2)]= [ML^(2)T^(-2)A^(-2)]`
`[Wb]= [ML^(2)T^(-2)A^(-1)], [(Wb)/(m^(2))]= [MT^(-2)A^(-1)]`
`["henry"]= [ML^(2)T^(-2)A^(-2)], [(H)/(m^(2))]= [MT^(-2)A^(-2)]`
Obviously henry (H) has dimensions `[(ML^(2))/(Q^(2))]`
