Consider a system which is initially in the state , (o)= E (0, o) + VY,., Ex. ueoyinoil otye fuhabd Y,, (0, ). The expectation value of L, is 5 1 Lonthaud l) 4/6 (B) (A) h 5 36 h (D) 6h (C) 5 Sol. (B) We have wave function ve. o) = (,,)+Yo (0.0)+Y(00) om The x-component of angular momentum can be written as ,-i Therefore, the expectation of value of L, 2 )-(WC)
