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.
How do you attract paper?
Basically, when an electrification takes place, electrons are not created but they are transferred….. in the case of comb attracting tiny tiny bits of papers when rubbed with dry hair is because electrons from the dry hair gets transferred to the comb and now the comb induces a dipole in the bitties of paper and the …
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.
How can a charged plastic comb attract neutral pieces of paper?
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.
What form of energy is produced when comb?
With a comb , static electricity is produced.
How do you show charge by induction using a comb and water?
On the right side, the water stream is attracted towards the positively charged comb. 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.
Why would torn paper be more attractive to the comb that cut paper?
Charge accumulates more easily on sharp points rather than edges. Torn pieces of paper have more sharp points (look at it under a magnifying glass, or better yet, a microscope!) compared to cut paper.
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.
How can you explain a comb run through dry hair attracts pieces of paper?
When a comb rubhed with dry hair attracts pieces of paper. This is because the comb induces a net dipole moment opposite to the direction of field. This happens the field due to charge on comb induces dipole moment in paper by tretching or re-orienting molecules of the dielectric.
How Electric forces and electric fields interact in pieces of paper attracted by comb?
Explanation: When you rub the comb on your hair electric charges are accumulated on it, but the charge distribution is localized. This means that the electric field is non-uniform. This electric field polarizes the paper pieces and there are both positive and negative polarization charges.
Why does a charged rod attracts paper?
H5UUvely Chusu If we take a positively charged glass rod near small pieces of paper, the rod attracts the pieces. … This is because the positively charged rod attracts the electrons of a paper piece towards itself. Some of the electrons accumulate at that edge of the paper piece which is closer to the rod.
How do you charge a plastic comb?
If you hold a plastic comb in your hand and rub it in your hair, it will get charged. However, if you do the same with a metal comb it will not get charged.
Does a metal rubbed hair attract pieces of paper?
with plastic scale it is possible, because rubbing it with your hair generates static electricity – as plastic is a bad conductor of electricity. where as metal scale absorbs electrons and hence it doesn’t generate that effect. Bits of paper are dielectric and get attracted through dielectrophoretic force.
When a plastic comb is charged by rubbing it with a cloth?
Question: When an object such as a plastic comb is charged by rubbing it with a cloth, the net charge is typically a few microcoulombs.
