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

A

`Wb//m^(2)`

B

`"Henry (H)"`

C

`H//m^(2)`

D

`"Weber (Wb)"`

Text Solution

Verified by Experts

The correct Answer is:
B
`"Mutual inductance"=(phi)/(I)=(BA)/(I)`
`["Henary"]=([MT^(-1)Q^(-1)L^(2)])/([QT^(-1)])=ML^(2)Q^(-2)`
