- 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?arrow_forwardMost workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting −50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 29 steps and what is the maximum number of steps that any worker should be allowed to take before touching the components if a delicate manufacturing process can be damaged by an electrical discharge greater than 1012 electrons? Make sure to answer both parts of the question.arrow_forwardMany 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…arrow_forward
- 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?arrow_forward(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 8.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. 236000000000 X You can approach this problem as a unit conversion exercise in that you need to convert grams of silver to electrons using the information given in the problem as conversion factors (b) Imagine adding electrons to the pin until the negative charge has the very large value 1.00 mC. How many electrons are added for every 109 electrons already present? X 5.30 Note that 109 is one billion. It might help to rewrite your answer from part (a) as the number of billions of electrons.

During a lightning storm, a charge of 19.3 coulombs travels through this potential difference.

(b) Calculate the amount of charged moved, Q, in coulombs.arrow_forwardLong, long ago, on a planet far, far away, a physics experiment was carried out. First, a 0.250-kg ball with zero net chargewas dropped from rest at a height of 1.00 m. The ball landed0.552 s later. Next, the ball was given a net charge of 7.75 mC anddropped in the same way from the same height. This time theball fell for 0.680 s before landing. What is the electric potentialat a height of 1.00 m above the ground on this planet, given thatthe electric potential at ground level is zero?
