If one were to apply Bohr model to a particle of mass ‘m’ and charge ‘q’ moving in a plane under the influence of a magnetic field ‘B’, the energy of the charged particle in the nth level will be :

Question

$\begin{array}{1 1} n \bigg( \frac{hqB}{2 \pi m} \bigg) \\ n \bigg( \frac{hqB}{4 \pi m}\bigg) \\ n \bigg( \large\frac{hqB}{8 \pi m} \bigg) \\ n\bigg( \frac{hqB}{\pi m}\bigg) \end{array} $
