Question

What happens when an ebonite rod is rubbed with the fur?

Answer 1

Work is the energy delivered to or from an item by applying force along a displacement in physics. It is frequently expressed as the product of force and displacement in its simplest form. When applied, a force is said to produce positive work if it has a component in the direction of the point of application's displacement. If a force has a component that is opposite the direction of displacement at the point of application, it produces negative work.

Complete answer:
Triboelectric effect refers to the phenomenon of charging caused by rubbing.
When you touch an ebonite rod with fur, it becomes negatively charged because the friction between the fur and the rod causes the ebonite rod to acquire one electron from the fur. This is due to the fact that electrons in fur are less securely linked than those in ebonite rods.
Electrons are removed from the atoms in the glass rod and transferred to the silk cloth when you rub it with the silk fabric. As a result, the glass rod has a net positive charge, with more positive than negative charge.
As a result, ebonite and glass rods will attract one another.
A chemical connection is created between specific portions of the two surfaces when we brush fur with an ebonite rod. Rod has a more firmly bonded electron than hair. As a result, fur contributes electrons to the rod, while electrons from the rod remain trapped. The rod becomes negatively charged due to an overabundance of electrons, whereas the fur with lost electrons becomes deficient in electrons. Fur becomes positively charged as a result.

Note: Ebonite rod is a type of vulcanised rubber rod.
When you rub the ebonite rod with your fur, electrons are transferred from the fur to the ebonite rod.
Ebonite has a negative charge because the electrons in fur are less firmly linked than those in ebonite.
The ebonite rod has a negative charge, whereas the fur has a positive charge.
