In this Chapter we will the force acting Lesson 3:. Uses of Electrostatics. (part 1). Starter. Solve the following anagrams (all connected with charge and electrostatics):. cattis. chosk. desplad. garech. raid rifle bolt. rathe. regyne. ANSWERS. Electric Force. Whiteboard Particle Model . (remember sticky tape lab?). H. ow . you can . make a balloon stick on the wall?. What is occurring on the atomic level that lets you do this?. The atom. The atom has positive charge in the nucleus, located in the protons. . Examples of Electrostatics in the world are. :. A doorknob shock. Static in the dryer. Your hair standing up when combed. What is electrostatics? (644). Electricity at . rest. Involves electrical charges, the forces between them, and their behavior in materials. Units of Chapter 16. Static Electricity; Electric Charge and Its Conservation. Electric Charge in the Atom. Insulators and Conductors. Induced Charge; the Electroscope. Coulomb’s Law. Solving Problems Involving Coulomb’s Law and Vectors. Essential Knowledge. 1.B.2. : There are only two kinds of electric charge. Neutral objects or systems contain equal quantities of positive and negative charge, with the exception of some fundamental particles that have no electric charge.. If you rub a balloon . on . your . arm . more. , . the size of the charge will . ( decrease / increase ).. An object loses electrons and becomes . ( positively / negatively ). charged.. If . you charge two objects by rubbing them on your arm, they will have . 1. When the balloon is rubbed on the sweater, what might happen?. A. . Some positive charges in the sweater will move onto the balloon. B. Some negative charges in the sweater will move onto the balloon. G S Peter Castle, LFIEEE and William D . Greason. , LFIEEE.

Make a top (T1) and bottom (B1) tape sandwich. Make another pair of top and bottom tapes (T2 & B2). Directions. Hang T1 and B1 off the end of the table. (see figure below). 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..
