Why the pieces of paper get attracted to the ruler?

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.

Why do tiny bits of paper get attracted?

Tiny bots of paper undergo electrostatic force , when you rub a comb or pen or anything which is plastic. Therefore they get attracted to the thing which you have rubbed.

THIS IS MAGNIFICENT:  What are the 3 basic factor of a tourist destination?

Is paper positively or negatively charged?

The bits of paper are electrically neutral, but when you bring the rod close to them, even though paper is not a conductor, that is, the charges within it are not free to move about as a current, the negative charges have enough mobility that they are repelled by the rod.

Why does a rubbed comb attract bits of paper?

Initially the comb is electrically neutral. So it has no effect on the tiny pieces of paper. When the comb is rubbed on a dry cloth, it gets electrically charged. This charged comb exerts an electric force on the tiny pieces of paper and attracts them.

Why does paper being neutral is still attracted by charged plastic scale?

6 Answers. This is because the neutrality of polarity can be changed by electric field in this case. When you create – charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be -.

What force is acting on the pieces of paper before the ruler is brought close to them?

When the ruler is brought close to bits of paper, the attractive electric force accelerates the paper bits upward against the force of gravity.

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

Initially, the comb is electrically neutral. So it has no effect on the tiny pieces of paper. When the comb is rubbed on a dry cloth, it gets electrically charged. This charged comb exerts an electric force on the tiny pieces of paper and attracts them.

THIS IS MAGNIFICENT:  Question: What are the four factors that an entrepreneur looks at in measuring the attractiveness of a business opportunity?

When a charged plastic ruler is brought close to small pieces of paper they get attracted to it this is due to charging by Dash?

It is due to electrostatic force in which the uncharged body attract the another uncharged or charged body and this force is generated.

How does an object become positively charged?

An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.
