Comb attracts a bits of paper because Comb is charged object and paper is in neutral so, to be charged one must be in neutral and Comb is negative charged as it gains electrons from hair. Since ,when Comb is placed near to a bits of paper then papers get charged due to induction.
Can a metallic aluminum comb attract pieces of paper?
ANSWER: The paper is initially attracted to the comb because the comb causes separation of charge in the paper. The part of the paper pieces with positive charge is attracted to the comb.
Can plastic comb attract paper?
Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper.
Why does paper stick to the comb?
The comb has become charged by friction, acquiring an excess of electrons. … This leaves a net positive charge on the side close to the comb, and since unlike charges attract, the paper is attracted to the comb.
Why is hair attracted to comb during a hot day?
The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. … If two objects have different charges, they attract (or pull towards) each other.
Why do apples not repel each other?
Every apple contains equal numbers of negative and positive charges, therefore they appear neutral to each other.
When a comb is rubbed in your hair it acquires?
Complete step by step answer:irstly, when the comb is used to rub dry hair, it always acquires a negative charge or electron which the hair carries, where the comb is induced with the electron gotten from the hair then immediately the comb which is negatively charged comes in contact with the piece of paper which is …
What is the charge of your hair if you comb your hair and the comb become positively charged?
The material that gains electrons becomes negatively charged while the material losing electrons becomes positively charged. The comb is positively charged implying the hair should be negatively charged. If you comb your hair and the comb becomes positively charged, then your hair becomes negatively charged.
What happens when you rub a comb on a piece of wood?
We often comb longer with a wooden comb because it feels so good. The massaging action stimulates the follicles to produce more hair strands, increasing hair growth and producing thicker hair.
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.
What is the charge on the comb or nylon?
The molecules orientate their dipoles, the negative oxygen towards the comb; the positively charged hydrogens away from it. When you comb your hair with a nylon comb, both the comb and your hair become charged.
Which force makes a charged comb attracts small pieces of paper?
When the charged comb is brought near bits of paper, the electrostatic force of attraction between the atoms of the paper and the comb caused by the electrons on the surface of the comb polarizes them which attracts the pieces of paper towards the comb.
Why do combs get charged?
These atoms contain equal number of protons and electrons so they are uncharged. So the surface of any object made of atoms has electrons, which are negatively charged. When the comb is rubbed against the cloth the electrons move between the two, and the comb gets charged.
Why does paper stick to my hand?
Paper sticks easily to a wet finger because of the principal covalent bonding. This is the same reason water does not spill over the edge of a glass if it’s slightly overfilled, or another example of covalent bonding is how two pieces of glass will stick together when they’re wet.
