Zeke Says That the Magnitude of the Orbital Angular Momentum

Multiple Choice

Zeke says that the magnitude of the orbital angular momentum in the hydrogen atom has the value L =
) Ruth says that the maximum magnitude of the projection of the angular momentum along the direction of a constant magnetic field vector
Is
) Which one,if either,is correct,and why?

A) Ruth,because the maximum value of L is .
B) Ruth,because the orbital angular momentum always lines up with a magnetic field so that has its maximum value along the field.
C) Zeke,because the maximum magnitude of is L = .
D) Zeke,because the orbital angular momentum always lines up with a magnetic field so that has its maximum value along the field.
E) Neither,because they have interchanged the maximum magnitude of , ,and ,its maximum projection along a magnetic field direction.
