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.

Ground your electroscope. Touch a negatively charged rod to the metal plate of the electroscope. Draw in the schematic how the charges are distributed, and indicate the new deflection of the rotating pointer once it has come to equilibrium + Perform this experiment with the charge remaining from step 3. Recharge your negatively charged object and bring it into close proximity to the metal plate without touching. We are charging by induction in this case. How does the...

A positively-charged plastic rod is brought close to (but does not touch) a neutral metal sphere that is connected to ground. After waiting a few seconds, the ground connection is removed (without touching the sphere), and after that the rod is also removed. The sphere is now A) negatively charged. B) positively charged. C) neutral.

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...
