How do they compare with the corresponding energies in the absence of the delta function? explain why the odd solutions are not affected by the delta function. comment on the limiting cases α → 0 and α → ∞

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?
