In the figure below an electron is shot directly toward the center of a large metal plate that has surface charge density - 1.20 x 106 C/m². If the initial kinetic energy of the electron is 4.80 × 10-17 Jand 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? Number i ! Units 3

A parallel-plate capacitor has a charge Q and plate separation d, as shown below. We assume that the size of plates is much larger than the separation d. Each particle is initially at rest and then released, allowing it to accelerate.  Assuming each particle has the same mass, rank the speeds of the particles when they impact the left plate. 1.
