Question

a rod is rubbed wih a material that has a greater affinity for electrons than the rod does, explain in terms of electrons and charging

Answer 1

The material will gain some electrons will become negatively charged (because electrons are negatively charged ) but the rod loses those electrons, so the rod will become positively charged.

Answer 2

then this rod is brought near a neutral electroscope

Answer 3

The electroscope will undergo induced polarization and will be attracted towards the rod.

Answer 4

then this rod touches the electroscope and is removed

Answer 5

Electroscope will be charged by losing electrons

Answer 6

don't u think, when this rod touches the electroscope there is a process of conduction?

Answer 7

Actually, I meant, "Electroscope will be charged by losing electrons to the rod." So, there is conduction for a very small fraction of time.

Answer 8

Is that okay ?

Answer 9

it's meanwhen the rod is removed there is no conduction?

Answer 10

now a positive rod alternately brought near the electroscope then??

Answer 11

Yes, when the rod is removed there is no conduction.
I don't understand "positive rod alternately brought near the electroscope".

Answer 12

positively charged rod

Answer 13

Are you carrying the rod near to the electroscope and then carrying it away from it and then again carrying near it and so on..?

Answer 14

with your help now i think i can easily make my assignment thank u sooo muchhh

Answer 15

:)
