The figure above shows a very large nonconducting plate that has a uniform surface charge density σ =5 μC/m2; it also shows a point charge Q = -2 μC at distance d = 0.4 m from the plate. Both are fixed in place. We choose the origin of an x-axis at Q. At what positive coordinate on the x-axis (other than infinity) is the net electric field Enet=0? ______m
An infinite plane of charge has surface charge density 5.8 μC/m2. How far apart are the equipotential surfaces whose potentials differ by 100 eBook
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 6.40 × 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? Please explain your reasoning, thank you!
