What is the Electric Field Between Deflection Plates in a TV Tube?

In summary, the first conversation discusses the use of two charged plates to steer an electron beam in a TV tube. The force experienced by the electron is given as 3.ox10^-6 N, and the question asks for the magnitude of the electric field between the plates.The second conversation revolves around a charged globe being dusted off by a custodian, resulting in a charge of -8.0x10^-9 C. The question asks for the magnitude and direction of the electric field at a point 0.40m away from the center of the globe. In both conversations, the concept of electric fields and their effects on charged particles is being discussed.

Homework Statement


An electron beam in the TV tube is steered across the screen by the field between two charged plates. If the electron experiences a force of 3.ox10(to the negative 6th)N, how large is the field between the deflection plates?



2. Homework Statement
The custodian dusts off a globe with a duster, causing the globe to acquire a charge of -8.0x10(to the negative 9th)C. What is the magnitude and direction of the electric field at a point 0.40m from the center of the charged globe?

FAQ: What is the Electric Field Between Deflection Plates in a TV Tube?

1) What is electrostatic energy and why is it important?

Electrostatic energy is a type of potential energy that results from the buildup of electric charges. It is important because it plays a crucial role in many natural phenomena, such as lightning, and is also used in many technological applications, such as generators and motors.

2) What are some common sources of electrostatic energy?

Some common sources of electrostatic energy include friction, separation of materials, and electrical devices such as batteries and capacitors.

3) What safety precautions should be taken in case of an electrostatic emergency?

If you are experiencing an electrostatic emergency, it is important to stay calm and avoid contact with any potential sources of electrostatic energy. You should also avoid using any electrical equipment and seek professional help immediately.

4) How can electrostatic energy be controlled?

Electrostatic energy can be controlled through various methods, such as grounding, shielding, and ionization. These techniques help to dissipate the buildup of electric charges and prevent potential hazards.

5) What are some potential dangers associated with electrostatic energy?

Some potential dangers of electrostatic energy include electric shocks, fires, and explosions. It is important to handle and control electrostatic energy with caution to avoid any potential hazards.
