toward the center of a large metal plate that has
surface charge density -1.20 x 10-6 C/m². If the initial
kinetic energy of the electron is 4.80 × 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?
