Question: An electron is released from rest at the negative plate of a parallel plate capacitor. When released, it accelerates toward the positive plate and strikes it with a velocity of 1.5 x 10^6 m/s. If the separation distance between the plates is 4.0 cm, what is the surface charge density on each plate?
