Question

Name the type of force which acts in the following cases: A comb rubbed with silk attracts the bits of paper.

Answer 1

There is a phenomenon called electrostatic charge, when you rub a comb on hairs or anywhere else, it creates a charge, either $+ ve$ or $- ve$ charge. When you bring the comb near pieces of paper, the respective charge created on the comb attracts the opposing charge on the pieces of paper.

Complete answer:
The electrostatic force between particles is an attracting and repulsive force induced by their electric charges. The electrostatic force is the electric force between two charged things that are stationary. Coulomb's force is another name for it.Now let us understand the matter. This is due to the fact that rubbing the comb charges it.

Atoms, which are minuscule uncharged particles, make up everything we see around us. These atoms are uncharged because they have an equal number of protons and electrons. As a result, any object consisting of atoms has negatively charged electrons on its surface.Like charges repel one another, while unlike charges attract each other, as many of us know about this.

When the comb is brought near neutral paper strips, the same thing happens. Depending on whether the comb has a negative or positive charge, electrons are either repelled or attracted within the paper strips. The paper strips then have an opposite charge in the direction of the comb, causing them to rise towards it. Electrostatic force is the charge that is formed when two items rub against each other.

Note: Lightning is another type of electrostatic force, but it is displayed on a much larger scale. When the particles in the clouds rub against one other, they gain charge, and the equalising charge is sent to earth, which is a neutral area to dump charges.
