A electron of mass, `m_(e)` revolves around a nucleus of charge `+Ze`. Show that it behaves like a tiny magnetic dipole. Hence, prove that the magnetic moment associated with it is expressed as `vec(mu) = - (e )/(2m_(e)) vec(L)`, where `vec(L)` is the orbital angular momentum of the electron. Give the signification of negative sign.

Explanation

Apply magnetic moment and orbital angular momentum concept.
