A nonrelativistic electron is accelerated from rest through a potential difference.
 
  After acceleration the electron has a de Broglie wavelength of 880 nm. What is the potential difference though which this electron was accelerated? (h = 6.626  10-34 J  s, e = - 1.60  10-19 C, mel = 9.11  10-31 kg)
  A) 2.5 V B) 2.2 V C) 1.9 V D) 1.7 V

Question 2

An electron is released from rest at a distance of 9.00 cm from a fixed proton.
 
  How fast will the electron be moving when it is 3.00 cm from the proton? (k = 1/40 = 8.99  109 N  m2/C2, e = 1.60  10-19 C, melectron = 9.11  10-31 kg, mproton = 1.67  10-27 kg)
  A) 75.0 m/s
  B) 106 m/s
  C) 130 m/s
  D) 1.06  103 m/s
  E) 4.64  105 m/s
