Question

An electron of mass m e ​ and charge − e ( e > 0 ) moves in a closed orbit in a uniform magnetic field B acting perpendicular to the plane of the orbit. If Bohr's quantisation rule for angular momentum were to be applied to this system, the minimum magnetic flux (of the applied magnetic field B) passing through the orbit equals
