What happens when a glass rod is rubbed with silk?

By convention, we call one type of charge “positive”, and the other type “negative.” For example, when glass is rubbed with silk, the glass becomes positively charged and the silk negatively charged. A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged.

Are glass and silk insulators?

Because the glass rod is an insulator, it must actually touch the electroscope to transfer charge to or from it. (Note that the extra positive charges reside on the surface of the glass rod as a result of rubbing it with silk before starting the experiment.)

Does a glass rod become positively charged when rubbed against Cotton?

If you rub a glass rod with a cloth, the charge produced on the glass rod is called positive, whereas when a plastic rod is rubbed with a cloth, the charge produced on the plastic rod is negative.

When a glass rod is rubbed with silk It Mcq?

The glass rod gains protons from silk when they are rubbed against each other. The glass rod gains electrons when they are rubbed against each other.

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.

What happens when a plastic rod is rubbed with fur and glass rod rubbed with silk?

A plastic rod when rubbed with fur becomes negatively charged and a glass rod when rubbed with silk becomes positively charged.

Is glass an insulator?

In addition to being a good electrical insulator, glass has many other useful properties. It is a good thermal insulator (most material are either both or neither), and it is resistant to many corrosive chemicals. Because of their lack of crystal structure, glasses are sometimes called amorphous materials.

Is silk an insulator?

Among the mentioned options silk is an insulator. This is because copper is a very good conductor of electricity and so is the human body. This is because of the enormous amount of free electrons present in these materials.

What happens when a positively charged rod is touched to a negatively charged rod?

To make a negatively charged rod grounded the electrons go from the hand to the ground. What happens when a positively-charged rod is touched to a negatively-charged rod? Some electrons will travel to the positively charged rod. These electrons attract to the wall, which is neutrally charged.
