1.(8pt)Consider the normalized trial wavefunction: \(\psi = 2ce^{-cr}\) as a solution to the hydrogen atom problem that has radial Hamiltonian: \(\hat{H} = \hat{T} + \hat{V} = -\frac{\hbar^2}{2m}\left[\frac{d^2}{dr^2} + \frac{2}{r}\frac{d}{dr}\right] - \frac{e^2}{4\pi\epsilon_0 r}\) a.) Find a symbolic expression for the trial energy expectation value: \(\langle E \rangle = \int dr \psi^* \hat{H} \psi\) using the trial wavefunction (do NOT put numbers in the physical constants. Simplify your answer as best you can using the physical symbols and parameter c). Don't forget the radial integration factor is: \(\int dr = \int_0^\infty r^2 dr\)
