- A water molecule is made up of two hydrogen atoms and one oxygen atom, with a total of 10 electrons and 10 protons.

- (a) What is the final speed of an electron accelerated from rest through a voltage of 25.0 MV by a negatively charged Van de Graff terminal? (b) What is unreasonable about this result? (c) Which assumptions are responsible?arrow_forwardThe first Leyden jar was probably discovered by a German clerk named E. Georg von Kleist. Because von Kleist was not a scientist and did not keep good records, the credit for the discovery of the Leyden jar usually goes to physicist Pieter Musschenbroek from Leyden, Holland. Musschenbroek accidentally discovered the Leyden jar when he tried to charge a jar of water and shocked himself by touching the wire on the inside of the jar while holding the jar on the outside. He said that the shock was no ordinary shock and his body shook violently as though he had been hit by lightning. The energy from the jar that passed through his body was probably around 1 J, and his jar probably had a capacitance of about 1 nF. a. Estimate the charge that passed through Musschenbroeks body. b. What was the potential difference between the inside and outside of the Leyden jar before Musschenbroek discharged it?arrow_forwardLightning can be studied with a Van de Graaff generator, which consists of a spherical dome on which charge is continuously deposited by a moving belt. Charge can be added until the electric field at the surface of the dome becomes equal to the dielectric strength of air. Any more charge leaks off in sparks as shown in Figure P20.67. Assume the dome has a diameter of 30.0 cm and is surrounded by dry air with a breakdown electric field of 3.00 106 V/m. (a) What is the maximum potential of the dome? (b) What is the maximum charge on the dome? Figure P20.67 David Evison/Shutterstock.comarrow_forward
- 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_forwardHow many electrons should be removed from an initially uncharged spherical conductor of radius 0.300 m to produce a potential of 7.50 kV at the surface?arrow_forward(a) What is the energy stored in the 10.0 F capacitor of a heart defibrillator charged to 9.00103 V ?

- An election enters a region between two large parallel plates made of aluminum separated by a distance of 2.0 cm and kept at a potential difference of 200 V. The electron enters through a small hole in the negative plate and moves toward the positive plate. At the time the electron is near the negative plate, its speed is 4.0103 m/s. Assume the electric field between the plates to be uniform, and find the speed of electron at (a) 0.10 cm, (b) 0.50 cm, (c) 1.0 cm, and (d) 1.5 cm from the negative plate, and (e) immediately before it hits the positive plate.arrow_forward(a) Find the potential difference VB required to stop an electron (called a slopping potential) moving with an initial speed of 2.85 107 m/s.
