Many of a computer's internal components, such as the random access memory (RAM) and central processing unit (CPU), are very sensitive to electrostatic discharge (ESD). You have probably experienced ESDs yourself, if you have ever shuffled your feet across a carpeted floor and then touched a metal doorknob. You experienced a small shock, as the excess electrons you stripped from the carpet are transferred to the door knob. If the relative humidity in the room is low, the buildup of charge on the surface of your body, which acts like an insulator, can be significant-more than enough to damage a computer's components. To prevent ESDs, people assembling computers will wear antistatic equipment, such as that shown in the photo. The wrist strap is said to be grounded, which gives the static charge a safe conducting path away from the body, thereby protecting the computer components. In walking across a carpeted hallway, a computer technician acquires a charge of -4.79 x 10-⁹ C. Assume he touches one of the contact pins of a RAM module without wearing his antistatic equipment and completely delivers his excess charge through the component. How many electrons enter the RAM module during the discharge?

An electrophorus is a device developed more than 200 years ago for the purpose of charging objects. The insulator on top of a pedestal is rubbed with a cloth, such as wool (Fig. P23.18A). A conductor is placed on top of the insulator, and the conductor is connected to ground by a conducting wire (Fig. P23.18B). (The conductor has an insulating handle, so charge cannot be transferred between the person and the conductor.) The conductor is then removed (Fig. P23.18C). The conductor may then be used to transfer charge to other objects. If the insulators charge after being Ribbed with the wool is negative, what is the charge of the conductor when it is removed?
When your classmates open the door to exit your school's new fully carpeted theater, they frequently complain of unpleasant electric shocks. Write a letter to the principal about the problem, explaining the physics underlying the phenomena and offering modest improvements to the auditorium (at least near the door) to eliminate the annoyance (charging and discharging).
An electron with speed v0 = 3388829.6m/s travels parallel to and along the same direction as an electric field of magnitude E = 3154N/C. (a) How far will the electron travel before it stops?

An electron is initially at rest on the surface of a spherical conductor with a radius of 0.01 m and a charge of 1.6 femto Coulombs. What is the initial velocity required for this electron to escape from this sphere of conduct to a point infinitely far away and have zero kinetic energy there?
The membrane of a body cell has a positive ion of charge +e+e on the outside wall and a negative ion of charge −e−e on the inside wall. Determine the magnitude of the electrical force between these ions if the membrane thickness is 0.80×0.80×10−910−9mm. Ignore the effect of the material in which the ions are located. Fq=
An engineer is designing a process for a new transistor. She uses a vacuum chamber to bombard a thin layer of silicon with ions of phosphorus, each of mass mP = 5.18 × 10-26 kg. The phosphorus ions are doubly ionized, with each phosphorus ion lacking two electrons. The ions start at rest at one end of the vacuum chamber and are accelerated by an electric field over a distance of re = 59 cm before they strike the silicon layer with velocity vP = 185 m/s. a. Enter an expression for the potential difference ΔV, in volts, between the initial and final points across the vacuum chamber.
