An electron with kinetic energy 2.80 eV encounters a potential barrier of height 4.70 eV.
 
  If the barrier width is 0.40 nm, what is the probability that the electron will tunnel through the barrier?
  (1 eV = 1.60  10-19 J, mel = 9.11  10-31 kg, h = 1.055  10-34 J  s, h = 6.626  10-34 J  s)
  A) 3.5  10-3
  B) 7.3  10-3
  C) 1.4  10-2
  D) 2.9  10-3
  E) 3.5  10-2

Question 2

A particle confined in a rigid one-dimensional box (an infinite well) of length 17.0 fm has an energy level En = 2.0 MeV and an adjacent energy level En+1 = 37.5 MeV.
 
  What is the value of the ground state energy? (1 eV = 1.60  10-19 J)
  A) 1.50 MeV
  B) 13.5 MeV
  C) 0.500 MeV
  D) 4.50 MeV
