Like Charges:

* Repel: Two objects with the same type of charge (both positive or both negative) will push each other away. Imagine two magnets with the same poles facing each other – they'll resist being brought together.

* Example: If you rub two balloons with a wool cloth, they'll both become negatively charged and will fly apart when brought close together.

Unlike Charges:

* Attract: Two objects with opposite charges (one positive and one negative) will pull towards each other. Think about two magnets with opposite poles facing each other – they'll snap together.

* Example: If you rub a balloon with a wool cloth (making it negative) and then bring it near a wall, the wall will become temporarily positive due to the attraction of the opposite charges, causing the balloon to stick.

In a Nutshell:

* Like charges repel - they push away from each other.

* Unlike charges attract - they pull towards each other.

This fundamental principle of electromagnetism is responsible for a vast array of phenomena in the universe, from the bonding of atoms to the operation of electrical devices.
