Problem: In an electron gun, electrons are accelerated from the cathode toward the anode, which is at a potential higher than the cathode. If the potential difference between the cathode and anode is 12 kV, at what speed do the electrons move as they reach the anode? Assume that the initial kinetic energy of the electrons as they leave the cathode is negligible.
