If $m$ is mass, $'Q'$ is charge and $B$ is magnetic induction $\large\frac{m}{BQ}$ has same dimension as

\[(a)\;frequency \quad (b)\;\frac{1}{frequency}\quad (c)\;velocity \quad (d)\;acceleration \]

Can you answer this question?

Dimension of B is $[ M T^{-1} C^{-1}]$
Therefore $\large\frac{BQ}{m}$  has dimensions of $\large\frac{1}{time}$ and
Hence $\large\frac{m}{BQ}$ has dimensions of $\large\frac{1}{frequency}$
