1. A flat metal plate has a uniform surface charge density of 3E-9 C/m^2. A second flat metalplate, parallel to the first, has an equal and opposite surface charge density. The two areclose enough together that they can be modeled as infinite planes. How much pressure(force per square meter of surface) is required to pull them apart? How much work (persquare meter of surface) is required to separate the plates by a distance of 1 cm?×と4.

Problem 12: A simple and common technique for accelerating electrons is shown in the figure, which depicts a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to pass through. E = 2.4 × 104 N/C Calculate the horizontal component of the electron's acceleration if the field strength is 2.4 × 104 N/C. Express your answer in meters per second squared, and assume the electric field is pointing in the negative x-direction as shown in the figure.
