When Rubbing A Plastic Ruler With Cloth The:?

By rubbing the ruler with a cloth, electrons will be transferred from the cloth to the ruler, causing the ruler to become negatively charged due to the accumulation of electrons in its surface.

What happens when an insulator such as a plastic ruler is rubbed with a cloth and gains a negative charge?

Insulating materials can get electrically charged if they come into contact with one other and rub against each other. Electrons, which have a negative charge, are able to be transferred from one substance to another by a process known as ″rubbing.″ The substance will grow more electronegative as it accumulates more electrons.

When a plastic ruler is rubbed?

6. A flannel cloth is used to massage the surface of a plastic ruler. It acquires a negative charge as a result. Page 8 Describe the process by which the ruler acquires the charge. Electrons are transferred from the fabric onto the ruler whenever the ruler is touched with the cloth.

What happens when a plastic comb is charged by rubbing it with a cloth?

The electrons that are removed from the wool’s atoms end up being rubbed onto the surface of the plastic ruler, which becomes covered with them.When you use a plastic comb on your hair, you get the same result as described above.The plastic comb has acquired an excessive amount of negative electric charge as a result of the accumulation of additional electrons that have just become adhered to it.

What force is generated when a plastic ruler is rubbed with a woolen cloth?

Charges are generated by rubbing the plastic ruler with the woolen fabric since this causes friction. Because of the electrostatic force, these charges are transferred from the object to the paper.

Does plastic lose or gain electrons when rubbed?

Wool is a substance that is very good at giving up electrons, and plastic is very good at picking up these electrons that wool has given up. As a result of this, the plastic will acquire a negative charge when we brush the wool across it.

What happens when a plastic ruler is rubbed with wool and then brought near a pile of paper scraps?

They have charges that are opposing to one another, which causes them to attract one another. wool on a ruler results in a fresh force of attraction being generated between the ruler and the fragments of paper. When the ruler is brought into close proximity to bits of paper, the attractive electric force causes the bits of paper to speed upward in opposition to the force of gravity.

Why does a plastic ruler that has been rubbed with a cloth have the ability to pick up small pieces of paper?

The negative charge of the ruler polarizes the charge already present on the paper, which means that, in a nutshell, it draws in the positive charges and pushes out the electrons. A sufficient amount of electric force is generated, and the paper is lifted!

Does the ruler gain or lose electrons?

The ruler is now positively charged (meaning it lacks electrons), whereas the fabric has a negative charge due to the ruler’s extra electrons (i.e.is electron deficient).If you tally up all of the positive and negative charges at the beginning and then again at the conclusion, you will find that there are still the same amount of them; this indicates that the total charge has been preserved!

Why is there a need to rub the comb with a piece of cloth or through your hair?

When you run a comb through your hair, electrical charges are transferred from your hair to the comb. As a result, the comb acquires a charge, which can be either positive or negative, and the hair acquires an opposing charge.

Is wool positively or negatively charged?

It appears that certain sorts of items are more capable than others of getting charged. Silk has a tendency to impart a positive charge to items, whereas wool has a tendency to impart a negative charge.
