What happens when you rub a metal rod with silk?
The core has positive charge, the electrons have negative charge. When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth.
When you rub a glass rod with a silk cloth electrons are transferred from the?
When the glass rod is rubbed with silk clothes, glass quickly loses electrons, and silk takes electrons out of the glass rod. So after rubbing, the glass rod becomes positively charged and the silk gets negative charge.
Why are electrons not transferred from silk cloth to glass rod?
No electron travels from glass rod to the silk cloth. when a glass rod is rubbed it acquires positive charge and similarly when a silk cloth is rubbed it acquires negative charge they attract each other whereas no electron transfer takes place.
What happens when you rub a balloon with silk?
When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity.
What particles are transferred from the cloth to the rod when it becomes charged?
When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be ‘rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged.
How is glass rod charged positively when rubbed with silk?
When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.
Why do electrons transfer on rubbing?
Molecules in the fur have a stronger attraction for electrons than the molecules in the rubber rod. During a charging by rubbing (or by friction) process, the material that becomes negatively charged does so because it simply likes electrons more than the material with which it is rubbed.
What is the role of the rubbing process in the activity?
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons cling to your body until they can be released.
How is charge transferred from a ruler to a metal rod?
For example, this ruler has a negative charge. When the ruler is broughı near the inetal knob, it repels electrons in the metal. Electrons move away froni the ruler and down the metal rod. The knob now has a positive charge.
How do electrons move from one material to another?
During this friction, the surface atoms of both the materials are pressed together bringing the electron clouds to a closer proximity thereby causing an interaction, which results in the transfer of electrons among the clouds.
What happens when a glass rod is rubbed with silk cloth?
When a glass rod is rubbed with silk cloth then some of the electrons from the glass rod get transferred to silk cloth and thus the glass rod get transferred to silk cloth gets negative charge. No new charge is created in the process of rubbing.
What is negative electrification of silk?
Negative electrification is due to the excess of electrons (compared to the normal number of electrons in a neutral atom).For example, on rubbing a glass rod with silk, the electrons from the glass rod get transferred to the silk. The silk now has an excess of electrons and so is negatively-charged.
