Explanation:

When we talk about charges, there are two types of charges - positive and negative. Like charges refer to two charges that are of the same type, either both positive or both negative. On the other hand, unlike charges refer to two charges that are of different types, one positive and one negative. The behavior of like and unlike charges can be explained by the concept of electric forces.

Like charges:
When two charges are of the same type, i.e., both positive or both negative, they exert a force on each other. This force is known as the electric force. Like charges repel each other, meaning they push away from each other. This repulsion occurs because like charges have the same electrical polarity, and according to the law of electric charges, similar charges repel each other.

Unlike charges:
On the other hand, when two charges are of different types, i.e., one positive and one negative, they also exert a force on each other. Unlike charges attract each other, meaning they pull towards each other. This attraction occurs because unlike charges have opposite electrical polarity, and according to the law of electric charges, opposite charges attract each other.

Summary:
- Like charges (same type) repel each other.
- Unlike charges (different types) attract each other.

Examples:
- Two positive charges will repel each other.
- Two negative charges will repel each other.
- A positive charge and a negative charge will attract each other.

This understanding of like and unlike charges and their behavior is essential in understanding the principles of electricity and the behavior of objects in an electric field.
