Il ACTIVITY NO: 1 Module 1: Electricity Lesson: Force of Electricity. Electrical Potential. and Capacitors 3. Dielectrics i. If LED 1: 102 electrons move through a pocket calculator during a full day's operation. how many coulomb's of charge moved through? ||- mm 2. When a glass rod is rubbed with silk. it becomes positive and the silk becomes negativevet both attract dust. Does the dust have a third type of charge that is attract to both positive and negative? Explain. 3. Why does car always attract dust right after it is polished? (Note that car wax and tires are insulators.) III. ggglomb' g law 4. A negative charge of -2.0 C and a positive charge of 3.0 C are separated by 80 m. What is the fOrce between the two Charges? 5. A negative charge of 4.0 x 105 C and a positive charge of 10 x lOr-'i are separated by 0.15 m. hat is the force between the two charges? 6. Two negative charges that are both -.5.0 x 10-5 C push each other apart with a force of IS N. How far apart are the two charges? IV- mm; 7. Voltages are always measured between two points. Why? V.
