rticle ofmass mina potential V =-kr, and with anadded perturbation H' = E a. Find the first order correction to the energy of the nth state. b. Are there non-zero 2nd order corrections to the energy? Explain. c. Are there values for n where the first order correction breaks down? Explain physically why this makes sense. Are there any similarities of the answers to parts a and c to problem #3? Are the physical reasons the same? Comment. d.
