Why are tiny bits of paper attracted to a charged rubber rod or balloon?

The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a negative charge. The positively charged fibers are now attracted to the negatively charged balloon. The negatively charged balloon attracts the paper.

Why tiny bits of paper are attracted to a charge rubber rod?

Answer. The charges in the paper are polarised. Those of similar charge to the excess charge on the rod are repelled and those of opposite charge are attracted. This leaves an area of opposite charge near the rod and so since the paper scraps are so light they can be lifted up by this attraction.

Why is paper attracted to the rod?

A positively charged rod is brought near a piece of paper. … When the positively charged rod is brought near the neutral paper, it induces a negative charge on the side of the paper nearer to the rod. Since unlike charges attract each other, the paper will be attracted to the rod.

Why are bits of paper attracted towards a charge body?

The paper is attracted to the comb. This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb. … The charges move from one insulator to another on vigorous contact (i.e. by rubbing) to produce the two oppositely charged objects.

Why small pieces of paper are attracted by a glass rod which is rubbed with a cloth explain clearly the physics involved in this observation?

Rubbing the glass with the silk charges the glass positive, and the glass rod thus charged attracts the paper bits in the same way that the plastic rod does. … This leaves a net negative charge on the material that has gained electrons, and a net positive charge on the material that has lost electrons.

How does a charged ruler attracts small pieces of paper?

When the negatively charged ruler is brought near to the paper pieces, they are attracted to the ruler as the the electrons move around on the paper because of the large charge on the ruler. Electrons will move away from the ruler leaving a positive charge on the paper near the ruler, so they are attracted.

What is charging by friction?

Charging by friction: the transfer of electrons from one uncharged object to. another by rubbing the two objects together. Some electrons can move to the. other object when rubbing (hair and balloon) Charging by conduction: the transfer of electrons from one object to another by.

Why do electrified rods attract?

Answer: When electrified rods are brought near light objects,the rods induce opposite charges on the near surfaces of object as well as on farther side of object. … Thus the electrified road attracts light objects.

How can a charged plastic comb attract neutral pieces of paper?

Objects can get charged when rubbed together with different objects. When you run a plastic comb through your hair, the comb gets charged due to friction – the plastic loses some electrons. Then when you place the comb near small pieces of paper, the paper pieces are attracted to the comb.

Why do tiny bits of paper get attracted when brought close to a plastic comb which have recently been rubbed?

Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body.

Why do tiny bits of paper get attracted when brought close to comb?

This happens because when comb is rubbed with hair there occurs a transfer of electrons from hair to the comb. Thus the comb gets negatively charged,when the charged comb is brought near the bits of paper it attracts the positive part of it.

When a plastic comb is rubbed in dry hair it attracts tiny pieces of paper which force is involved in this process?

Electrostatic force is involved in this process.

Why does a plastic comb rubbed with dry hair attract tiny pieces of paper?

Why is a glass rod positively charged?

When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. … On rubbing together, the glass rod loses 2 electrons and silk gains 2 electrons. Now the glass rod has 8 electrons and 10 protons which makes it positively charged.

Why does the charged suspended glass rod show attraction towards the charged Ebonite Rod?

When an ebonite rod is rubbed with fur it starts gaining electrons and therefore obtains negative charge and when glass rod is rubbed with silk cloth it starts losing electrons and therefore obtains positive charge. Therefore, by the law of static electric charges, two opposite charged objects attract each other.

Why does a glass rod becomes positively charged when rubbed with silk?

When the glass rod is rubbed with silk, the silk strips electrons from the rod, leaving it a positive charge. When the hard rubber rod is rubbed with wool, it gains electrons from the wool, gaining a negative charge.
