electric charges
1. When a rod of the same charge is rought close to the knob of a charged metal leaf electroscope, what is the effect on the metal leaves? Draw a sketch that explains that effect.
2. When a rod of the opposite charge is brought close to the knob of a charged metal-leaf electroscope, what effect does this have on the metal leaves? Again, draw an explanatory sketch.
3. what is the procedure for giving an electroscope a positive charge by conduction.
4. What is the procedure for giving an electroscope a positive charge by induction?
5. how does an electroscope appear when it is (Draw a picture)
a) neutral
b) positively charged
c) negatively charged
Homework Answers
3. charging by conduction is
done by direct contact. so, we touch the metallic cap with charged
rod then there is conduction of charge from charged rod to
electroscope,charge reach the leaf of electroscope and the
separation between the leaf occurs.
4.charging by induction is done by bringing charged object near the metallic cap of electroscope. as there is electromagnetic induction due to charge of object. So opposite charge of object develops at the metallic cap and opposite at the leaf of electroscope.

a) You're holding a small metal ball suspended on a piece of insulating string from the ceiling. You and the ball are both initially electrically neutral. A positively charged rod is brought near to the metal ball; you then let go of the metal ball. You now have a positive electric charge. This process is called charging by 1.) Electroscope. 2.) Insulation. 3.) Conduction. 4.) Induction. b) Charged glass and plastic rods hang by threads. An object attracts the glass...

1. For each statement select P for Positive, N for Negative, or Z for Zero charge (Neutral). (If the first answer is positive, the second negative, and the third neutral (zero net charge), enter PNZ. Do not enter spaces) A) A negatively charged rod is brought close to a neutral isolated conductor, but it does not touch. The conductor is then grounded while the rod is kept close. If the ground connection is first broken, and THEN the rod is...
