The Nature of Electricity: Electric Charges and Force

The video tutorial explains the concept of electric charge, which is not visible but can be observed through its effects. Atoms can have either a positive or negative charge, influencing how they interact. Oppositely charged particles attract each other, while like charges repel. This is demonstrated using charged spheres and magnets, illustrating the fundamental principle that unlike charges attract and like charges repel.

Can you explain the concept of repulsion in terms of electric charge?

Summarize the relationship between unlike charges and like charges.
