Which of the following best describes the behavior of unlike charges?

Unlike charges, which refer to positive and negative charges, exhibit an attractive behavior towards each other. This attraction occurs due to the fundamental principle of electrostatics, which states that opposite charges attract while like charges repel. In the case of unlike charges, the positive charge exerts a force that pulls the negative charge closer, resulting in a mutual attraction.

This concept is pivotal in understanding various electrical interactions and is foundational in physics and electrical engineering. This behavior is critical in applications ranging from the basic operation of simple circuits to the functioning of complex electrical devices and systems. In summary, the attraction between unlike charges is key to the principles of electric forces and fields that govern electric interactions.
