Electric Charge and Repulsion

Introduction

Electric repulsion is a fundamental concept in physics that describes the interaction between charged particles. When two particles have the same type of electric charge, they experience a repulsive force, pushing them apart. In this article, we will explore the concept of electric repulsion and identify the pair of particles that exhibit this phenomenon.

Electric Charge and Repulsion

Electric charge is a fundamental property of matter that causes particles to interact with each other. There are two types of electric charges: positive and negative. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative or negative-positive) attract each other.

Types of Particles and Their Charges

To understand which pair of particles exhibits electric repulsion, we need to know the charges of different particles. The main particles involved in this discussion are electrons, protons, neutrons, and positrons.

Electrons: Electrons are negatively charged particles that orbit the nucleus of an atom.
Protons: Protons are positively charged particles that reside in the nucleus of an atom.
Neutrons: Neutrons are neutral particles that reside in the nucleus of an atom.
Positrons: Positrons are positively charged particles that are the antiparticles of electrons.

Electric Repulsion Between Particles

Now that we know the charges of different particles, let's identify the pair of particles that exhibits electric repulsion.

A. Electron and Proton: Since electrons are negatively charged and protons are positively charged, they attract each other, not repel.
B. Proton and Neutron: Since protons are positively charged and neutrons are neutral, they do not exhibit electric repulsion.
C. Electron and Electron: Since both electrons are negatively charged, they repel each other.
D. Neutron and Electron: Since neutrons are neutral and electrons are negatively charged, they do not exhibit electric repulsion.

Conclusion

In conclusion, the pair of particles that exhibits electric repulsion is the electron and electron. This is because both particles have the same type of electric charge, causing them to repel each other.

Key Takeaways

Electric repulsion occurs when two particles have the same type of electric charge.
Like charges (positive-positive or negative-negative) repel each other.
Opposite charges (positive-negative or negative-positive) attract each other.
The pair of particles that exhibits electric repulsion is the electron and electron.

Introduction

Q: What is electric repulsion?

A: Electric repulsion is the interaction between charged particles that causes them to push each other apart. It occurs when two particles have the same type of electric charge, such as two positive charges or two negative charges.

Q: What type of particles exhibit electric repulsion?

A: Particles with the same type of electric charge exhibit electric repulsion. This includes:

Like charges: Positive-positive or negative-negative charges repel each other.
Opposite charges: Positive-negative or negative-positive charges attract each other.

Q: What is the pair of particles that exhibits electric repulsion?

A: The pair of particles that exhibits electric repulsion is the electron and electron. Since both electrons are negatively charged, they repel each other.

Q: Why do like charges repel each other?

A: Like charges repel each other because they have the same type of electric charge. This causes them to push each other apart, rather than attracting each other.

Q: Why do opposite charges attract each other?

A: Opposite charges attract each other because they have different types of electric charge. This causes them to pull each other together, rather than pushing each other apart.

Q: Can electric repulsion occur between particles with different charges?

A: No, electric repulsion cannot occur between particles with different charges. Only particles with the same type of electric charge exhibit electric repulsion.

Q: What is the strength of electric repulsion between particles?

A: The strength of electric repulsion between particles depends on the magnitude of the charges and the distance between them. The greater the magnitude of the charges and the closer they are, the stronger the electric repulsion.

Q: Can electric repulsion be overcome by other forces?

A: Yes, electric repulsion can be overcome by other forces, such as gravity or the strong nuclear force. However, in most cases, electric repulsion is the dominant force between charged particles.

Q: What are some real-world examples of electric repulsion?

A: Some real-world examples of electric repulsion include:

Like charges repelling each other: When two positively charged objects are brought close together, they repel each other.
Opposite charges attracting each other: When a positively charged object is brought close to a negatively charged object, they attract each other.

Conclusion

In conclusion, electric repulsion is a fundamental concept in physics that describes the interaction between charged particles. By understanding the basics of electric repulsion, we can better appreciate the complex interactions between particles in the universe.
