Consider the Two Time-Dependent Spin State Vectors Shown Below These State Vectors Are Physically Equivalent

True/False

Consider the two time-dependent spin state vectors shown below:
$$\begin{aligned}& \left|\psi_{A}\right\rangle=\sqrt{1 / 2}|+z\rangle-\sqrt{1 / 2} e^{-i E t / \hbar}|+z\rangle \\& \left|\psi_{B}\right\rangle=\sqrt{1 / 2} e^{+i E t / 2 \hbar}|+z\rangle-\sqrt{1 / 2} e^{-i E t / 2 \hbar}|+z\rangle\end{aligned}$$
These state vectors are physically equivalent.
