What natural phenomenon can be caused by two like-charged objects?

The correct answer is the concept of repulsion. When two like-charged objects are brought close to each other, they exert a force that pushes them apart. This is a fundamental principle of electrostatics: like charges repel each other. For example, if you have two objects charged with positive charge, they will repel each other, moving away from one another due to the electric field they create.

Understanding this concept is crucial for grasping how electric forces work in various applications, from everyday static electricity to more complex electrical systems. The idea of repulsion is foundational in understanding charge interactions and is essential knowledge for anyone studying electrical concepts.
