An electron is fired directly toward the center of a large metal plate that has excess negative charge with surface charge density 2.00×10-6 C/ m2. If the initial kinetic energy of the electron is 50 eV and if the electron is to stop (owing to electronstatic repulsion from the plate) just as it reaches the plate, how far from the plate must it be fired?
