Does rubbing a polythene rod with a duster take away positive charge from the cloth?
no
How to charge an object by friction?
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.
What is a polythene rod?
Polythene is an abbreviated form of the word polyethylene, which is a common type of plastic. Plastic can be used to make a rod.
What will happen if a polythene rod rubbed with dry woolen cloth brought near another polythene rod also rubbed with a dry woolen cloth?
Both rods acquired charge of the same polarity during the rubbing process, so there will be a force of repulsion between them.
When a polythene rod is rubbed with a duster it becomes negatively charged . why?
Because electrons are rubbed off the cloth and build up on the polythene.

If you rub a copper rod rather than a polythene rod the copper rod will not stay charged why not?
because copper cannot conduct static energy but polythene can.

What charge develops on rubbing plastic straw with polythene?
Static electrical charge.
What happens when charged polythene rod come close together?
they repel one another
If you rub a polythene rod with a cloth will it become magnetic?
No, it will not become magnetic. It will become electrically charged.
When the perspex rod is rubbed with nylon and the rod becomes positively charge what charge will be on the nylon?
a negative charge
A plastic rod is rubbed with a dry cloth how does the rod become negatively charged?
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
