An electron beam is deflected upward through 3.0 mm while traveling in a vacuum between two deflection plates 12.0 mm apart. The potential difference between the deflecting plates is 100.0 kV and the kinetic energy of each electron as it enters the space between the plates is 2.0 Ã— 10ˆ’15 J. What is the kinetic energy of each electron when it leaves the space between the plates?
