Which statement about electrical charges is true?

The statement that like charges repel each other is fundamental to understanding electrical charges and their interactions. In physics, it is established that objects with the same type of electric charge—such as two positively charged particles or two negatively charged particles—will experience a force pushing them apart. This principle is a basic tenet of electrostatics and can be observed in practice, such as when two static-filled balloons are brought near each other; they will repel one another.

This behavior is crucial in various applications, from designing electrical circuits to understanding atomic and molecular structures. It underlines the concept of charge conservation and the interactions that govern the behavior of charged particles in electric fields. Understanding this principle is essential for anyone studying electrical engineering or related fields, as it lays the groundwork for more complex concepts in electromagnetism and circuit theory.
