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
