Chapter 19: Static Electricity Please remember to run off 4 pages onto one sheet by pass A3?A4 and victimisation tail to back on the photocopier If an fair game has to a greater extent electrons than protons it is contradictly aird, if the object lens has more protons that electrons so it is positively frissond)*. Opposite entrusts set; homogeneous ailments repel each other. You can demonstrate this by hang two oppositely charged rods as shown and throwaway that they both move towards each other. The symbol for charge is Q. The social unit of charge is the Coulomb symbol is C. The Gold Leaf Electroscope You must love the structure of an Electroscope and list some of its functions. If the GLE is uncharged, the leaves leave drop cloth together. If the leaves fail charged either positively or ostracisely the leaves will stand apart (why?). [pic]A = insulated joint, B = metal gaffe Functions: 1. To detect charge 2. To delineate betwee n positive and negative charge 3. To indicate approximate sizing of a charge 4. To test if an object is a conductor or an insulator How would you use an electroscope to demonstrate each of these?

Earthing If an object functions charged (due to a build-up of electrons say), and the object is whence countryed (connected to earth), the electrons will separate as a great deal as possible, resulting in just about of them quite literally going to earth. The object then becomes neutral. Charging a conducting object by Induction To Charge an Insulated manager Positively [pic] 1. Bring a negatively charge ob ject near the conductor; the positive and ne! gative charges become spaced on it. 2. Keeping the charged object in place, earth the conductor by touching it with your finger. 3. Some of the negative charge on the metal flows through you to earth. 4. Remove your finger, then and except then remove the rod. 5. The conductor will immediately be positively charged. You should now be able to shit the applicable diagrams to show how to charge an object negatively by...If you penury to get a full essay, order it on our website: BestEssayCheap.com
