eletrostáticas

Eletrostáticas refers to the study of stationary electric charges and the forces they exert on each other. This field is a fundamental part of electromagnetism. When objects accumulate an imbalance of electric charge, either a surplus or deficit of electrons, they become electrostatically charged. This charge can be positive or negative. Like charges repel each other, while opposite charges attract. This interaction is described by Coulomb's Law, which quantifies the force between two point charges. The strength of this force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

The presence of an electric charge creates an electric field around it. This field is a region of space where another electric charge would experience a force. Electric fields can be visualized using electric field lines, which indicate the direction and strength of the field. When a charged object is placed in an electric field, it experiences an electrostatic force. This phenomenon underlies many everyday occurrences, such as static cling on clothes, the operation of photocopiers, and the attraction of a balloon rubbed against hair. Understanding eletrostáticas is crucial for comprehending more complex electrical phenomena and for the design of various electrical devices.
