A hydrogen atom starts out in the following linear combination of the stationary states n = 2, l = 1, m = 1 and n = 2, l = 1, m = -1

(a) Construct Ψ(r, t). Simplify it as much as you can.

(b) Find the expectation value of potential energy, V. (Does it depend on t? Give both the formula and the actual number, in electron volts.
