An electron is released from rest at the negative plate of aparallel plate capacitor and accelerates to the positive plate (seethe drawing). The plates are separated by a distance of 1.3 cm, andthe electric field within the capacitor has a magnitude of 2.6 x106 V/m. What is the kinetic energy of the electronjust as it reaches the positive plate?
