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.
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.
Does photo copiers use static electricity to copy on to a page?
Yes. The ink sticks just as a rubbed comb attracts bits of paper.
Why does a comb drawn through hair attract a tiny piece of paper?
If a comb drawn through (dry) hair attracts a tiny piece of paper, it is almost certainly due to static electricity. We know that when some things are "rubbed" on other things, electrical charges can be displaced. A difference of potential is set up between two objects by moving charges from one object to another. And the difference of potential can, through electrostatic force, cause what is observed here.
Why a comb drawn through hair attracts a tiny piece of paper?
This is due to electrification process. As we rub the comb along with hair, the molecues in the comb would lose some electrons to the hair. This happens due to friction. So comb due to lack of negatively charged electrons becomes positively charged. Same time hair gaining electrons becomes negatively charged. Now as we keep this charged comb close to a bit of paper, then by electrostatic induction opposite charges here negative electrons are pulled towards it. So paper gets negative charge momentarily. Hence force of attraction between unlike charges. So paper bit gets attracted.
When you comb your hair and you put the comb with hair near the small piece of paper?
due to force of attraction b/w opposite charges

What kind of force can make a small piece of paper cling to a comb?
static electricity? dont really understand what exactly u mean

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.
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.
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 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.
What happens if you rub a comb on the jumper and hold it above some small pieces of tissue paper?
I don't exactly know, but I think the tissue paper will do something?
