What is the action of positive and negative particles when they are brought together?

When positive and negative particles are brought together, they exhibit the action of attraction. This phenomenon is rooted in the basic principles of electric charge, where opposite charges draw towards each other, resulting in a force of attraction.

In an electric field, positive charges are typically associated with protons, while negative charges are associated with electrons. When these two types of charges come close, the negative charge of the electrons exerts a pulling force on the positive charges of protons, leading to their attraction. This interaction is fundamental to various physical processes, including the formation of atoms, where electrons orbit positively charged nuclei.

Understanding this concept is vital for grasping the basics of electrostatics and electric forces, which are foundational topics in electrical applications.
