When positive and negative charges attract, it is called electrostatic attraction.
A more detailed response to your request
When positive and negative charges attract, it is called electrostatic attraction. This phenomenon occurs due to the interaction between charged particles, such as electrons and protons. Electrostatic attraction plays a fundamental role in the behavior of matter and is responsible for a wide range of natural phenomena.
Electrostatic attraction is rooted in the principle that opposite charges attract each other. According to this principle, positive charges are attracted to negative charges, while like charges repel each other. This force of attraction can be mathematically described using Coulomb’s law, which quantifies the strength of the electrostatic force between two charged particles.
Quote: “Every positive value has its negative; every negative value has its positive. The proverb teaches that there is an inherent and inseparable duality in all aspects of life.” – Jon Krakauer
Interesting facts about electrostatic attraction:
-
Lightning is a powerful example of electrostatic attraction. When clouds become charged, positive charges accumulate at the ground, while negative charges form in the lower portion of the cloud. The attraction between these opposite charges results in lightning strikes.
-
Static electricity is another everyday example of electrostatic attraction. It occurs when there is an imbalance of charges on the surface of an object, causing it to attract or repel other charged objects. Rubbing a balloon on the hair, for instance, creates static electricity that can cause the balloon to stick to the hair.
-
Van de Graaff generators are devices that utilize electrostatic attraction to accumulate high voltages. They can generate immense amounts of electrostatic charge, which are often used for scientific experiments or demonstrations.
-
The phenomenon of adhesion in nature, such as water droplets clinging to glass surfaces or spider webs, is a result of electrostatic attraction. The attraction between the charges on the molecules of different substances allows them to stick together.
Table:
| Phenomenon | Description |
|---|---|
| Lightning | Powerful discharge of electrostatic energy between clouds and the ground |
| Static electricity | Imbalance of charges on the surface of an object, resulting in attraction or repulsion |
| Van de Graaff generator | Device that accumulates high voltages using electrostatic attraction |
| Adhesion | Electrostatic attraction between different substances leading to sticking or clinging behaviors |
In conclusion, electrostatic attraction is a fundamental force that governs the behavior of charged particles. Its effects can be observed in various natural phenomena such as lightning, static electricity, and adhesion. As Jon Krakauer’s quote suggests, the concept of opposite charges attracting reflects a broader duality that exists in different aspects of life.
See a video about the subject
In this section of the video titled “Positive and Negative Charge,” Mr. Andersen discusses the concept of positive and negative charges. He demonstrates how a charged object, such as a balloon, can attract or repel other objects based on their charges. He also explains how a neutral object can become polarized when a charged object is nearby, creating an attraction between them. To further illustrate these concepts, Mr. Andersen employs a simulation. Overall, the video provides a clear explanation of positive and negative charges and their interactions.

This “separation of charge” is the reason for the collection of effects we call static electricity. If two objects have different charges, they attract (or pull towards) each other. If two objects have the same charge, they repel (or push away) from each other.
The term for attraction between positive and negative charges is ionic bond. Cations (ions with a positive charge) are attracted to anions (ions with a negative charge). Like charges repel each other, while unlike charges attract. The attraction or repulsion acts along the line between the two charges.
Chapter Review Cations (ions with a positive charge) are attracted to anions (ions with a negative charge). This attraction is called an ionic bond. In covalent bonds, the participating atoms do not lose or gain electrons, but rather share them.
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Electric charge can be positive or negative (commonly carried by protons and electrons respectively, by convention). Like charges repel each other and unlike charges attract each other. An object with no net charge is referred to as electrically neutral.
