The hydrogen atom described in Problem 8.16 is now subjected to a magnetic field having the same direction as that of the atom. Show that the forces caused by B result in a decrease of the angular velocity by eB/(2m_e) and a decrease in the orbital moment by e²a²B/(4m_e). What are these decreases for the hydrogen atom in parts per million for an external magnetic flux density of 0.5 T?
