Question

Bohr model is applied to a particle of mass m and charge $q$ is moving in a plane under the influence of a transverse magnetic field (B). The energy of the charged particle in the second level will be ( h = Planck's constant)

• A. $\frac{\text{qBh}}{\pi\text{m}}$
• B. $\frac{\text{q}^2 \text{B}^2 \text{h}^2}{4\pi\text{m}}$
• C. $\frac{\text{qBh}}{2\pi\text{m}}$
• D. $\frac{2q\text{Bh}}{\pi\text{m}}$

Hint:

Combining Bohr's angular momentum quantization with magnetic force leads to discrete energy levels for charged particles.
