What happens when you rub a glass rod with a silk cloth?
A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged.
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.
Why is silk negatively charged?
When a glass rod is rubbed with silk, electrons are transferred from the glass rod to the silk. Since the glass rod losses electrons, it becomes rich in positive charge. Similarly, the silk cloth becomes negatively charged.
When a glass rod is rubbed with silk The silk acquires?
A glass rod has free electrons which are less tightly bound, so when the rod is rubbed with silk it loses electrons to a silk piece. The glass rod has deficiency of electrons and acquires positive charge and the rod acquires negative charge.
Why can you charge a plastic rod by rubbing it with a cloth but the same process will not charge a metal rod?
Explanation: While you can charge a dielectric (non conductive, like plastic) object rubbing, you cannot charge a conductor (like a metal) rubbing. The reason is that in a metal the charges are free to move inside the material. So you can charge only some material rubbing.
Why do electrified glass rod and silk cloth when brought in contact no longer attract each other?
the surface of a glass is very smooth hence the electrons are very loosely attached to its surface . hence when a glass rod is rubbed against the silk cloth , glass rod looses electrons and become positively charged and the silk cloth becomes negatively charged.
Why is it that a glass rod that has been rubbed with silk was attracted to a hanging plastic rod that has been rubbed with wool?
The silk starts out with equal amounts of “glass charge” and “plastic charge” and the rubbing somehow transfers “glass charge” from the silk to the rod. Other objects, after being rubbed, attract one of the hanging charged rods (plastic or glass) and repel the other.
