(20 points) Treat the hydrogen atom as a one-dimensional problem, where the electron is confined to the diameter of the atom in the first excited state (n-2). a.) Use the uncertainty principle to estimate the minimum kinetic energy of an electron in this state, assuming that the uncertainty in position equal to it's diameter. (Note: Relativistic corrections are not necessary). b.) Assuming this excited electron only remains in this state for 0.1 ns, before emitting a photon and returning to...

An electron has a momentum p≈ 1.7×10−25 kg⋅m/s. What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (Δp/p) below 2.0%? Place final answer in 2 significant figures and convert answer to nanometers. The answer is NOT 15nm or 16nm from: x = h / [(4pi)(2%)(p)] = (6.626×10−34) / [(4pi)*(0.02)(1.7x10−25)]) = 15.5nm. Do not write this as the answer.
