Calculating Distance Between Charges Using Coulomb's Law

In summary, electrostatics is the branch of physics that studies electric charges at rest and the forces between them. Coulomb's law states that the force between two electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. An electric field is a region in space where an electric charge experiences a force, created by other electric charges. Electrostatic force is stronger than gravitational force and can be either attractive or repulsive. Some practical applications of electrostatics include generators, electric motors, air purifiers, photocopiers, and industrial processes such as painting and electroplating.

1. What is electrostatics?

Electrostatics is the branch of physics that deals with the study of electric charges at rest and the forces between them.

2. What is Coulomb's law?

Coulomb's law states that the force between two electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

3. What is an electric field?

An electric field is a region in space where an electric charge experiences a force. It is created by other electric charges and can be thought of as the influence of these charges on the surrounding space.

4. How is electrostatic force different from gravitational force?

Electrostatic force is the force between electric charges, while gravitational force is the force between masses. Electrostatic force is much stronger than gravitational force, but it can be either attractive or repulsive, while gravitational force is always attractive.

5. What are some practical applications of electrostatics?

Electrostatics has many practical applications, including in generators and electric motors, in air purifiers and electrostatic precipitators, and in photocopiers and laser printers. It is also used in industrial processes such as painting and electroplating.
