Conservation of Charges The conservation of charge states that the total electric charge in an isolated system never changes. The conservation of charge states that the total electric charge in an isolated system never changes. You can't create or destroy electric charge out of thin air. Charge can be transferred from one object to another, but the total amount of charge in the system stays the same. Quantization of charge You can't have half an electron's worth of charge. Any observed charge will always be a whole number multiple of the electron's charge. Quarks are the fundamental building blocks of protons and neutrons, which themselves make up the nucleus of an atom. There are six types (or "flavors") of quarks: up, down, charm, strange, top, and bottom. Meson- a quark-antiquark pair Baryon- combination of 3 quarks Antibaryon- three antiquarks Hadrons- mesons and baryons Tetraquarks- consist of 4 quarks Pentaquarks- 4 quarks and 1 antiquark Like charges Unlike charges repel attract F = is the force between two-point charges q1 and q2. r = distance between q1 and q2 k = a constant the medium, Equal to 9 x 10⁹ N.m²/C² Coulomb discovered that the electric force between two charges is: 1. Proportional to the product of the charges 2. And inversely proportional to the distance between them. 1. Proportional to the product of the charges means; If you double the charge on one object, the force between them will also double. 2. And inversely proportional to the distance between. This part signifies that as the distance between the two charged objects increases, the electric force between them decreases. For example, if you double the distance, the force will become one- fourth of its original value. In essence, Coulomb's Law tells us that: The stronger the charges, the stronger the electric force. The closer the charges are, the stronger the electric force.
