Although the bohr atomic model is in counting electrons in their orbitals, why is this model inaccurate in terms of the actual location and movement of electrons around an atom’s nucleus?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
