- An electron is shot directly toward the center of a large metal plate that has surface charge density σ = -2.0x10-6 C/m2. If the initial kinetic energy of the electron is 1.60x10-17 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?
- E → constant → constant F → constant acceleration
