The value of the commutator |, s (a) ihx y 14. The projection of the orbital angular momentum (L) of aectron on tne >-axis is gven by 4*",, nere the possiDNe values of 15 (b) 21+ a). (d) 2 15. The eigenvalue of 2-component of angular momentum ven by la) (+)h b) (+1h c) mh (d) m, 7n 16. The eigenvalues of are given by a) (+1)h(b) + 1)h )m (d) m,h 17. Which of the following commutators is correct? ()[4]= -ihy (d) All of these 18. The commutator |P=0 means that (a) both xX-com ponents of angular momentum and inear momentum are simultaneously measurable (b) both xcomponents of angular momentum and linear momentum are not measurable simultaneously c)either Xecomponent of angular momentum or xe comp onent of inear momentum is zero (G) None ot the above 19. If the Hamiltonian H=- . then |4,. H]= 2m dx (a) h (c)-1 20. The ladder operator L is defined as L, = L,+ily, then the commutator |,J has the value (a) L, ) ihl, (c) hl (d) hL,
