3. An electron is revolving around a proton in a circular orbit of radius r. The proton is assumed to be stationary. The total energy of this system is 1 e? E = 2m 4T€, r where p and m denote the momentum and mass of the electron, respectively. Take the radius r to be an estimate of the uncertainty in position Ar, and the uncertainty in momentum Ap to be an estimate of p. Suppose that ArAp= ħ when the system is in the ground state. Show that the ground state energy is given by 1 те4 E, = - 2 8h2 Give the numerical value for Ej in electronvolts. Discuss if your results are consistent with Bohr's model for the hydrogen atom.
