How far from the plate must the launch point be

Reference no: EM13285500

an electron is shot directly toward the center of a large metal plate that has surface charge density -1.00 × 10-6 C/m2. If the initial kinetic energy of the electron is 3.20 × 10-17 J and if the electron is to stop (due to electrostatic repulsion from the plate) just as it reaches the plate, how far from the plate must the launch point be?
