# What Happens When We Rub Glass Rod With Silk?

## What static electricity is produced by rubbing silk on a glass rod?

triboelectric effectWhen silk is rubbed on a glass rod, an electrostatic charge is generated in a phenomenon known as the triboelectric effect..

## What happens when you rub a rod with a cloth?

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.

## What happens when two glass rods are rubbed with silk and they are brought close to each other?

What happens when two glass rods are rubbed with silk and they are brought close to each other? They repel each other.

## What happens when you rub amber with a silk cloth?

When amber is rubbed with wool or silk, amber becomes positively charged. … (b) There are two types of charges and they are positive charge and negative charge. (c) Like charges repel each other while the unlike charges attract each other.

## When a glass rod is rubbed with silk It Mcq?

Answer: (b) The glass rod gives electrons to silk when they are rubbed against each other. 2.

## Is Amber positive or negative?

When glass is rubbed with silk the glass becomes positively charged. When amber is rubbed with fur the amber becomes negatively charged. All these things were neutral to start with, in other words they had equal numbers of positive and negative charges.

## What happens when you rub a glass rod 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.

## Why does a glass rod lose electrons when rubbed 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. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.

## When a glass rod is rubbed with silk cloth charges appear on both?

When a glass rod is rubbed with a silk cloth, opposite charges appear on both, because electrons are transferred from glass to silk. In this process, charge is not created or destroyed. It is merely transferred from one body to another. Hence, this observation is consistent with the law of conservation of charge.

## Why can a perspex rod be charged easier than a copper rod?

Shifting electric charges The surface of the plastic ruler gets coated with the electrons rubbed off the atoms in the wool. … This means the Perspex will not have enough electrons to balance the positive charge of the nucleus. Therefore, the Perspex rod will have an overall positive electric charge.

## How you could use a glass rod and piece of silk to determine the sign of the unknown charge on the object?

for identification of the sign of charge on the object we will bring the object near the glass rod, if it repels then charge on the object must be positive and if does not repels we bring the silk near the object and now, if it repels then the charge on the object must be negative.

## What happens when flannel is rubbed over a glass rod?

When glass rod is rubbed with flannel cloth, positive charges is produced.

## What is the best material to create static electricity?

The best combinations of materials to create static electricity would be to have one material from the positive charge list and one from the negative charge list. Examples include combining human skin with polyester clothes, combing your hair with a plastic comb, and rubbing fur on a Plexiglas rod.

## When we rub things they get charged This is called charging by?

The triboelectic charging process (a.k.a., charging by friction) results in a transfer of electrons between the two objects that are rubbed together. Rubber has a much greater attraction for electrons than animal fur.
