Question

Which of the following units denotes the dimension $\frac{M{L}^2}{Q^2}$ where Q denotes the electric charge?

• A. $Wb/m^2$
• B. $henry\left(H\right)$
• C. $H/m^2$
• D. $weber\left(Wb\right)$

Answer 1

The correct option is B $henry\left(H\right)$

Mutual inductance $=\frac{\varphi }{I}=\frac{BA}{I}$

$\left[Henry\right]=\frac{\left[M{T}^{-1}{Q}^{-1}{L}^2\right]}{\left[Q{T}^{-1}\right]}=M{L}^2{Q}^{-2}$
