the paper was a possitive charge
I think the answer sought was Physical Change. {and spelling got in the way.)
This depends on what the pieces of paper are up to. - If the pieces of paper are at rest on a surface, the normal (perpendicular) force of that surface is counteracting the attractive force of gravity. - If the pieces of paper are in the air, some aerodynamic forces are counteracting the attractive force of gravity, but only the component of the aerodynamic forces that is directed in the opposite direction of gravity. (That is, if you throw the pieces of paper UP in the air aerodynamics and gravity will do work in the same direction, and no force will counteract gravity.) This system is not in equillibrium and the pieces of paper will sooner or later fall to the ground. - It should be possible to counteract the attracting force of gravity by giving the pieces of paper an electrostatic charge and holding an object of opposite charge above them. This can be done by rubbing the pieces of paper against an inflated rubber balloon, the papers will stick to the balloon. Note that for this to work, something will have to counteract the force of gravity on the balloon. This can be done by suspending it from the roof or holding it in your hand. Something would then have to counteract the attractive force of gravity on the roof (the walls) or you (whatever you are standing on)... and so on ad infinitum...
Framed
The properties of a wooden ruler are: It has density, it can be flexible (the ones in the US are), it is light and it can help you in measuring measurable stuff. e.g. paper, height of water etc.
Well, there are two poles to a magnet. A negative one and a positive one. Since metals are good conductors of charge and the paper clip is a metal object, they will attract. The charge of the paperclip is opposite the charge to one of the poles of the magnet.
That is the static charge, which make a paper clip cling to a comb.
when rubbed with hair, ruler acquires some charge due to static electricity...becomes charged body and attracts tiny pieces of paper towards it.
Paper shredder made of multiple blades that shred the paper into strips or pieces. There are several types of paper shredders, each designed to shred papers differently, from simple and bigger strips to unrecognizable micro-sized pieces.
Piece of paper
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.
two pieces of paper
The answer depends on how small (or big) the pieces of paper are!
200,000 pieces of paper are in a ton

the bits of paper will stick on the wooden scale.
In the HQ, there's a rubber duck, a wooden hammer, and to the left of the wooden hammer is the paper.
