The energy of a proton is 1.0 MeV below the top of a 6.8-fm-wide energy barrier.
 
  What is the probability that the proton will tunnel through the barrier? (1 eV = 1.60  10-19 J,
  mproton = 1.67  10-27 kg, h = 1.055  10-34 J  s, h = 6.626  10-34 J  s)
  A) 0.051
  B) 0.048
  C) 0.056
  D) 0.053

Question 2

A 3.10-eV electron is incident on a 0.40-nm barrier that is 5.67 eV high. What is the probability that this 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) 1.4  10-3
  B) 9.0  10-4
  C) 1.0  10-3
  D) 1.5  10-3
  E) 1.2  10-3
