Items, such as plastics can easily become charge with when they are rubbed very quickly with a woollen cloth.. The electric force is one of the fundamental forces of nature. Controlled electricity is the cornerstone of our modern, technological society.. Chapter Goal: . To develop. a basic understanding of electric phenomena in terms of charges, forces, and fields.. .

All matter is made up of atoms. Atoms contain. Protons ( ). Neutrons (0). Electrons (-). Law of Electric Charges. The law of electric charges states . that like charges repel. , and . All Matter is Made of Atoms. Atoms consist of a nucleus made of particles called protons and neutrons, orbited by electrons. Atoms are Electrically Neutral. Atoms have the same number of protons ( ) and electrons (-) and have no charge. Chapter 21. © 2016 Pearson Education Inc.. Learning Goals for Chapter 21. Looking forward at …. how objects become electrically charged, and how we know that electric charge is conserved.. how to use Coulomb’s law to calculate the electric force between charges.. Charges are conserved. Charges are additive in nature. Charges are quantised.. PROPERTIES OF ELECTRIC CHARGES. PRODUCTION OF ELECTRIC CHARGE. We can get electric charge by three ways. By friction or rubbing. Coulomb's Law : . Coulomb's Law states that the force between two point charges Q. 1. and Q. 2. is directly proportional to the product of the charges and inversely proportional to the square of the distance between them..
