8. The observables Lr, Ly, L2 are incompatible since they do not commute, that is, [L, L] = ihL;; [Ly, L.] = iL;; [,, ] = %3D (Note that we can obtain these relations by cyclic permutations : r + y, y 2, z r). Show that these observables satisfy the Generalized Uncertainty Principle where oA is the variance of the observable such that it satisfies thato = ((A ())). %3D
