Let InI denote the energy eigenstates of a particle in a one-dimensional simple harmonic potential V(x)=-mox. If the particle is initially prepared in the state |y (1 = 0)) = (10) +|1)), the minimum time after which the oscillator will be found in the same state is (a) 3/(20) (b) /w (c) /(20) (d) 2/w
