What charge does a polythene rod acquire when rubbed with a duster?
A polythene rod acquires a negative charge when rubbed with a duster. This is because electrons are transferred from the duster to the polythene rod, leaving the rod with an excess of electrons and a negative charge.
Does rubbing a polythene rod with a duster take away positive charge from the cloth?
Rubbing a polythene rod with a duster can transfer electrons and create a charge imbalance (like triboelectric charging). If the polythene rod gains electrons during rubbing, it will become negatively charged, meaning the duster could potentially lose positive charge, but the overall charge conservation principle still applies.
What will happen if a polythene rod rubbed with duster brought near another polythene rod also rubbed with a duster?
The two polythene rods will repel each other. This is because when the rods are rubbed, they acquire a net positive charge which causes them to repel each other since like charges repel.
If you rub a polythene rod with a cloth will it become magnetic?
Rubbing a polythene rod with a cloth will not make it magnetic. This process of rubbing generates static electricity, not magnetism. Magnetism is a property of certain materials, such as iron and cobalt, that have aligned magnetic domains, which is different from the electrostatic charge generated by rubbing polythene.
When metal rod is rubbed against polythene bag or sweater it attracts or not?
When a metal rod is rubbed against a polythene bag or sweater, the rod becomes charged with static electricity. The metal rod may be attracted to the polythene bag or sweater due to the opposite charges present on each material.
What charge does a polythene rod acquire when rubbed with a duster?
A polythene rod acquires a negative charge when rubbed with a duster. This is because electrons are transferred from the duster to the polythene rod, leaving the rod with an excess of electrons and a negative charge.
If you rub a copper rod rather than a polythene rod the copper rod will not stay charged why not?
Copper is a good conductor of electricity, so when it is rubbed, any charge accumulated on its surface quickly redistributes throughout the rod and dissipates. This rapid conduction of charge prevents the copper rod from retaining a net charge like a polythene rod, which is an insulator and can hold onto excess charge more effectively.
Does rubbing a polythene rod with a duster take away positive charge from the cloth?
Rubbing a polythene rod with a duster can transfer electrons and create a charge imbalance (like triboelectric charging). If the polythene rod gains electrons during rubbing, it will become negatively charged, meaning the duster could potentially lose positive charge, but the overall charge conservation principle still applies.
Will a piece of perspex attract a polythene rod?
Yes, perspex can become attracted to a polythene rod when rubbed together due to the transfer of electrons between the two materials, resulting in a temporary static charge.
What is polythene rod made of?
The polymer "polythene".
What will happen if a polythene rod rubbed with duster brought near another polythene rod also rubbed with a duster?
The two polythene rods will repel each other. This is because when the rods are rubbed, they acquire a net positive charge which causes them to repel each other since like charges repel.

When a metal rod is rubbed against a polythene bag or sweater, the rod becomes charged with static electricity. The metal rod may be attracted to the polythene bag or sweater due to the opposite charges present on each material.
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.
When a polythene rod is rubbed with a duster it becomes negatively charged . why?
When polythene is rubbed with a duster, electrons from the duster are transferred to the polythene rod, giving the rod an excess of electrons and making it negatively charged. This transfer of electrons creates an imbalance of positive and negative charges on the surfaces, resulting in the rod becoming negatively charged.
Will a charged polythene rod repel or attract paper?
A charged polythene rod will attract paper. When the rod is charged, it develops an electric field that exerts a force on the charged particles in the paper, causing the paper to be attracted to the rod.
Why does polythene have a negative charge with a cloth?
When polythene is rubbed with a cloth, electrons are transferred from the cloth to the polythene, causing the polythene to become negatively charged. This transfer of electrons creates an imbalance of charges between the two materials, resulting in the polythene having a negative charge.
