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.
Why does plastic ruler attract pieces of paper when it is rubbed with dry hair?
Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body.
What happens when you rub a plastic ruler on your hair?
Shifting electric charges
The surface of the plastic ruler gets coated with the electrons rubbed off the atoms in the wool. The same effect is seen when you use a plastic comb on your hair. … Therefore, the Perspex rod will have an overall positive electric charge.
Why does a comb rubbed on hair attract pieces of paper?
You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of paper. 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.
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 does plastic attract hair?
After being rubbed together, the plastic in the balloon picks up a negative charge, while the person’s hair ends up with a positive charge. … This attraction between oppositely charged objects is what we know as ‘static’.
When plastic ruler is rubbed on hair develops force?
when the ruler is rubbed against dry hair , friction occurs between the two objects and electrostatic force is created.
What happens when a plastic ruler is rubbed with wool and then brought near a pile of paper scraps?
They have opposite charges and therefore attract each other. ruler with wool produces a new force of attraction between the ruler and bits of paper. When the ruler is brought close to bits of paper, the attractive electric force accelerates the paper bits upward against the force of gravity.
Does plastic lose or gain electrons?
Some materials like plastic, cloth, and glass do not give up their electrons easily. These are called insulators. Materials such as metals lose their electrons more easily and are called conductors. Since plastics are insulators, they are poor conductors of electricity.
Does a ruler gain or lose electrons?
The ruler is now negatively charged (i.e. has an excess of electrons) and the cloth is positively charged (i.e. is electron deficient). If you count up all the positive and negative charges at the beginning and the end, there are still the same amount, i.e. total charge has been conserved!
Why do tiny paper bits get attracted towards a plastic comb after the comb is rubbed against dry hair?
when plastic comb is rubbed with dry hair , it acquires charge due to static electricity and so it attracts pieces of paper which is uncharged.
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.
When a comb is rubbed against hair force generated in it is?
This is because the comb gets charged when it is rubbed. This charge that is created when two objects are rubbed against each other is called static electricity.
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 …
