HI PLS ANSWER
pieces of paper do not get attract therefore it not charged
Because electrons are rubbed off the cloth and build up on the polythene.
An object can be charged by friction when rubbed against another surface such asa) polythene rod rubbed against a woollen cloth.This occurred because the woollen cloth lost some of it negative charges when it was rubbed, the negative charges was then transferred to the polythene rod. Now the polythene rod has been charge by friction.For proof... after it has been charged,place the polythene rod next to some *very small bits of paper and see what happens.
a negative charge
HI PLS ANSWER
it attrarts paper :P
pieces of paper do not get attract therefore it not charged
The polythene becomes negatively charged.
Because electrons are rubbed off the cloth and build up on the polythene.

a negative charge
Both rods acquired charge of the same polarity during the rubbing process, so there will be a force of repulsion between them.
This happens because the negative electrons on the duster move to the polythene rod. Despite this, the rod still has some positive electrons meaning it should be called an unbalanced negatively charged rod. Hope this helps XD
no
it prevent it from turning brown
Nothing would happen
