A particle of mass m in a three-dimensional harmonic oscillator of poterntial energy (m w^2 r^2)/2 has spectrum given by E=h bar w(2nr+l+3/2) where nr is the radial quantum number and l is the orbital angular momentum suppose the particle has charge q and the harmonic oscillator is placed in a weak magnetic feild B. Sketch the energy spectrum for the three lowest energy states.
