What happens when a polythene strip is rubbed on a woolen cloth and then placed near a thin stream of running water from a tap?
The polythene becomes negatively charged.
What particles has a negative charge and which has a positive charge?
Negative charge = electron Positive charge = positron Positive charge = proton
What is a positive charge and particles called that have no charge?
A positive charge is a positive electrical charge. Particles with no charge are called neutral particles.
What is a positive charge plus a positive charge?
Two positive charges.
Does a proton have a A positive charge B negative charge or C no charge?
a proton has a positive charge
Does rubbing a polythene rod with a duster take away positive charge from the cloth?
no
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.
What kind of charge is produced in silk cloth when it is rubbed against a glass rod?
Positive charge
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?
Because electrons are rubbed off the cloth and build up on the polythene.
Will rubbing a silk cloth on glass cause electrons to move to the cloth?
Yes, rubbing a silk cloth on glass cause electrons to move to the cloth. As a result, glass rod acquires positive charge and silk acquires negative charge.
What charge develops on rubbing plastic straw with polythene?
Static electrical charge.
What happens when a polythene strip is rubbed on a woolen cloth and then placed near a thin stream of running water from a tap?
The polythene becomes negatively charged.
If a plastic ruler is rubbed with a cloth does the ruler obtain a positive charge?
Because electrons will be transferred from the cloth to the insulating rod. But the charge will be negative.
Why glass is charged positively when it is rubbed with dry cloth explain whether glass gains or loses electron when it is charged answer?
electrons are stripped away from the atoms in the glass and transferred to the cloth. This leaves the glass with more positive than negative charge, so you get a net positive charge.
If you rub a polythene rod with a cloth will it become magnetic?
No, it will not become magnetic. It will become electrically charged.
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
