Like charges (both positive or both negative) will 1. repel each other. This repulsion is due to the electrostatic force acting between them, which is described by Coulomb's law.
In contrast, unlike charges (one positive and one negative) will 2. attract each other.
In the case of magnetic forces, similar principles apply: like magnetic poles (north-north or south-south) will repel each other, while unlike poles (north-south) will attract each other.
Overall, the behavior of charged objects in electrostatic forces is characterized by the principle that like charges repel and unlike charges attract. For magnetic forces, like poles repel and unlike poles attract.
