1. A particle is confined to an infinite potential well of width ’L’. Calculate the probability
and energy of the particle between x=0 and x=L/4 in the first excited state?
2. Find the least energy of an electron moving in the dimension in an infinitely high
potential box of width 1˚A, given mass of the electron 9.11×10-31 kg and h =6.63×10-34 J.s.
