A nonrelativistic proton is confined to a length of 2.0 pm on the x-axis. What is the kinetic energy of the proton if its speed is equal to the minimum uncertainty possible in its speed? (1 eV = 1.60  10-19 J, h = 1.
 
  055  10-34 J  s, mproton = 1.67  10-27 kg)
  A) 5200 eV B) 5.2 eV C) 520 eV D) 0.52 eV E) 52 eV
