Some positive charges in the sweater will move onto the balloon. B. Some negative charges in the sweater will move onto the balloon. 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.. Chapter Summary 1. An electric field exists around any charged object. The field produces forces on other charged objects. . The electric field is the force per unit charge.. Creating and Measuring Electric Fields. 18.1 . The Origin of Electricity. The electrical nature of matter is inherent. in atomic structure.. coulombs. 18.1 . The Origin of Electricity. In nature, atoms are normally. found with equal numbers of protons. 4. . Two protons in an atomic nucleus are typically separated by a distance of 2 × 10. –. 15. m. The electric repulsion force between the protons is huge, but the attractive nuclear force is even stronger and keeps the nucleus from bursting apart. What is the magnitude of the electric force between two protons separated by 2.00 × 10. Physicists have identified four fundamental forces that account for the account all phenomena in the universe. .* . Force. Strength. Distance of action. Description. Strong nuclear. Very. strong!.
