A free electron is placed between two large, parallel, nonconducting plates that are horizontal and 7.83 cm apart. One plate has a uniform positive charge; the other has an equal amount of uniform negative charge. The force on the electron due to the electric field Upper E Overscript right-arrow EndScripts between the plates balances the gravitational force on the electron. What are (a) the magnitude of the surface charge density on the plates and (b) the direction of Upper E Overscript right-arrow EndScripts?

An electron is located half way between two parallel metal plates that are separated by a distance of 1cm. The inner surface of each plate (i.e., the surface that faces towards the other plate) has an area of 50cm×50cm. The left plate carries a charge +1µC and the right plate carries a charge −1µC. Suppose that the electron is moved a distance 0.1cm in the direction towards the negative plate. By how much does the electrostatic potential energy of the...
