What will happened to the sand if you placed the balloon rubbed with woolen cloth near it?
the sand would stand up
What is the charge when rubbing styrofoam with cloth?
A static charge of electricity will be the result.
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 happen when a plastic ruler rubbed vigorously with woolen cloth?
Both get charges oppositely. So they would attract each other if we bring them closer
What is a damp cloth?
A damp cloth is a piece of cloth that is slightly wet.
What kind of charge is produced in silk cloth when it is rubbed against a glass rod?
Positive charge
What type of electric charge is acquired if a rubber balloon is rubbed with a woolen cloth?
Static charge
Explain clearly what happened when Thales rubbed the amber with the silk cloth?
it created an electrical charge
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.
What happened when thale rubbed the amber with silk cloth?
when amber is rubbed with silk cloth +ve charge comes on silk cloth and -ve on amber due to interaction between their molecules, so is that when we comb our hairs , then -ve charge comes on comb and +ve on hairs,so when we bring silk cloth near the comb they attract each other due to 'ving opposite charges
What kind of electric charge gets developed on the glass rod when it is rubbed with a piece of silk cloth?
When glass rod is rubbed with silk cloth it becomes positively charged and the silk cloth becomes negatively charged. This is because the glass rod looses electrons to the silk cloth which makes it positive and the silk cloth becomes negative.
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 balloon is rubbed with a wool cloth it becomes negatively charged why?
When a balloon is rubbed with a wool cloth, the electrons from the atoms of the wool cloth enter the atoms of the balloon and thus, the number of electrons in the atoms of balloon becomes more than the number of protons. Hence, there is a net negative charge in the balloon, whereas in the wool cloth the number of electrons in its atoms become less than the number of protons, hence there is a net positive charge on the wool cloth.
What will happen if a glass ruler is rubbed vigorously on a woolen cloth?
A plastic ruler is rubbed vigorously with a woolen cloth
Can an insulator be charged?
Insulating materials can acquire a static electric charge. Rubber balloons, when rubbed on woolen cloth, are a perfect example.
When a balloon is rubbed with a wool cloth why does it become negatively charged?
When a balloon is rubbed with a wool cloth, the electrons from the atoms of the wool cloth enter the atoms of the balloon and thus, the number of electrons in the atoms of balloon becomes more than the number of protons. Hence, there is a net negative charge in the balloon, whereas in the wool cloth the number of electrons in its atoms become less than the number of protons, hence there is a net positive charge on the wool cloth.
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.
