Why does a comb attract pieces of paper even when it is not charged?

Nope, this does not contradict coulomb's law. 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.

∙ 14y agoCharge can be seen relatively here. Does the plastic have a negative charge? Or is it the paper which har a positive charge with regard to the plastic? Well, it doesn't matter, as the difference counts. Different charges attract each other. This is a result of nature being lazy and always trying to keep energy levels as low as possible, by means of elimination.

∙ 10y agothe comb must still have a residual charge on it to do that. try dampening the comb before trying again.

Why can they not use metal combs instead of plastic combs to attract pieces of paper?
Since the metal comb is a conductor, any charges you're able to place on it are conducted straight to your body as soon as you pick it up. So the comb never accumulates enough charge to exert much electrostatic force on the shreds of paper.
Why is hair attracted to a comb?
Hair is attracted to a comb because of the buildup of static electricity on the comb and on the hair. This buildup occurs when you pass the comb through the hair, and can be reduced or eliminated by adding a little bit of water to the comb or to the hair. Depending on the material of the comb, either the comb will be positively charged and the hair negatively charged, or it could be the other way around. Since opposing charges attract each each, the hair then is attracted to the comb.
What about the comb?
There are so many different types of combs. There's a rose comb, pea comb, single comb, v-shaped comb, walnut comb and a buttercup comb just to name a few.
If you charged the end of a comb and then put the same kind of charge on one place on the surface of a round metal ball on an insulating stand what would happen to the charge in each case?
,
What will happen to a piece of paper that contains positive charge if close to the comb contains the negative charge?
It will cause a chain reaction that will wipe out all life on Earth.
Why can rubber rubbed with wool attract small bits of paper?
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.
How does using a comb attract little pieces of paper?
the teeth catch the paper
Why doesn't an iron comb attract pieces of paper?
It is only after a build up of static electricity in the iron comb that will cause paper to be attracted to the comb.
How does a charged comb affect bits of paper?
The bits of paper acquire opposite charge of the comb and as unlike charge attract the bits of paper are attracted and picked up by the comb
Why doesn't an iron body attract pieces of paper?
Because it is a more dense solid. (heavier mass per size)
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
How do you explain why a charged comb often attracts smaller bits of papers that fly away when they touch the comb?
Static electricity in the comb attracted the slightly charged paper to it, but when the paper touched the comb, their very slight charge was neutralized, which caused them to fall off.
What is the magic behind when we comb dry hair it attracts pieces of paper?
It's called static electricity. Static charges can attract or repel other static charges.
When you place a comb in bits of paper it does not stick but if you run the comb through your hair it sticks after combing your hair?
yesYou created a static electrical charge on the comb, causing it to attract the bits of paper.
Charging by friction eg?
When we rub the hair with a comb then charges could be produced on the comb. When this comb is taken near by a bit of paper then that piece would be attracted towards the charged comb.
