Two very large parallel metal plates, separated by 0.20 m, are connected across a 12-V source of potential. An electron is released from rest at a location 0.10 m from the negative plate.
 
  When the electron arrives at a distance 0.050 m from the positive plate, how much kinetic energy has the electron gained? (e = 1.60  10-19 C)
  A) 7.2  10-19 J B) 2.4  10-19 J C) 9.6  10-19 J D) 4.8  10-19 J
