The reason why the pieces of paper are neutral is that they contain equal amount of positive and negative charges and so they cancel each other out.

When you bring a charged plastic comb to the pieces of paper, the charge opposite to that of the plastic comb will be brought to a part of the surface of the paper where the plastic comb is. Opposite charges attract each other, and since you're holding the comb, the pieces of paper will be attracted to the comb.

When Eraser is rubbed with wool do it attract piece of paper?

When an eraser is rubbed with wool, it becomes charged with static electricity. This charge can attract small pieces of paper due to the phenomenon of electrostatic attraction. The rubbing action transfers electrons from the wool to the eraser, giving the eraser a negative charge, which then attracts the positively charged paper bits.


Will a comb rubbed on the hair once attract bits of paper very they come close?

Yes, rubbing a comb on the hair creates static electricity which can attract small bits of paper when they come close. The electric charge on the comb will cause the bits of paper to stick to it momentarily.


Will a comb rubbed on the hair once attract pieces of paper everytime they are brought near?

no , because it is a temporary .the charge will remain displaced for 1- 3 Min's


Why is it difficult to do on humid day a plastic ruler that has been rubbed with cloth have the ability to pick up small pieces of paper?

On a humid day, the air is more saturated with moisture, making it harder for objects to build up an electrostatic charge, as the moisture helps to dissipate the charge. When a plastic ruler is rubbed with cloth, it gains a negative static charge that allows it to attract small pieces of paper that are neutrally charged. The moisture in the air reduces the effectiveness of the ruler’s static charge, making it more difficult to pick up the paper.


Why does a pencil leave a mark on paper?

When a pencil is rubbed on paper fiction causes a small amount of the graphite from the core of the pencil to be left on the paper. This leaves a visible mark.


Why does eraser became smaller when rubbed?

When an eraser is rubbed against paper, the friction between the eraser and the paper causes small particles of the eraser to break off. These particles stick to the paper, leaving a mark and making the eraser appear to shrink in size. This process is known as abrasion.


When a glass rod is change and is placed near small bits of paper the paper bits are attracted to the rod and then replied explain?

When a glass rod is rubbed, it acquires a positive static charge. The small bits of paper become negatively charged by induction when the positively charged glass rod is brought nearby. Opposite charges attract, causing the paper bits to be attracted to the rod.


Would small pieces of tissue paper near a rubbed balloon why would they probably stick to the balloon?

Yes, small pieces of tissue paper would likely stick to a rubbed balloon because the balloon becomes charged with static electricity when rubbed, creating an attractive force between the balloon and the tissue paper. This attraction is due to the transfer of electrons from one surface to another, resulting in static cling between the two materials.


A plastic rod will pick up small pieces of paper when it has been rubbed with a cloth?

When the plastic rod is rubbed with a cloth, it becomes charged with static electricity. The rod becomes positively charged by stripping electrons from the cloth, making it attractive to the small pieces of paper which are negatively charged. This electrostatic force allows the plastic rod to pick up the small pieces of paper.


Why a ruller will attract pieces of papers?

when you rub the plastic ruler on e.g. a yellow duster it takes the electrons (which is the negative charge) from the yellow duster and the plastic ruler becomes negatively charged. The paper has both protons and electrons the protons are positively charged. and very much like a magnet the negative is attracted to the positive hence the paper sticks to the ruler Hastings Tarrant


What experiment can you do toshow whether a plastic rod has changed or not?

You can rub the plastic rod with a piece of cloth and then try to attract small pieces of paper such as tissue paper or small paper bits. Repeat this process multiple times. If the plastic rod has gained or lost charge, its ability to attract the paper will change, indicating a change in the rod.


What happens when a straw is rubbed with your body?

Rubbing a straw against your body transfers electrons from your body to the straw, giving the straw a net negative charge due to an excess of electrons. This charge imbalance can cause the straw to attract lightweight objects like small pieces of paper or dust.
