The expectation value of position and momentum of a particle having normalized wave function vr) = n exp (a) (r=0 (p.)0 (6) ()=0 p.)=hk (c) hk p.)=0 d)( hk p.)h

answer is b because expection value of momentum of real wave function is zero always .but here wave is not real then expectation value of momentum has some answer and expectation v...
