Final answer:
The energy of a charged particle in the nᵗʰ level when applying the Bohr model to a particle of mass 'm' and charge 'q' moving in a plane under the influence of a magnetic field 'B' can be calculated using the formula: E = n(hqB)/2πm.
Step-by-step explanation:
The energy of a charged particle in the nᵗʰ level when applying the Bohr model to a particle of mass 'm' and charge 'q' moving in a plane under the influence of a magnetic field 'B' can be calculated using the formula:
E = n(hqB)/2πm
Here, n is the principal quantum number, h is Planck's constant, q is the charge of the particle, B is the magnetic field strength, and m is the mass of the particle.
Therefore, the correct option is A. n(hqB/2πm).
