An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate (see the drawing). The plates are separated by a distance of 1.5 cm, and the electric eld within the capacitor has a magnitude of 2.5 x 106 V/m. What is the kinetic energy of the electron just as it reaches the positive plate? Electric field eTextbook and Media Save for Later Attempts: 0 of 5 used
