Most of the time, in an object, its negative and positive charges are balanced, which makes it a neutrally-charged object. Sometimes, when some objects come into contact with other things, they gather more charges of one type. If there are more electrons, they are negatively-charged. If there are more protons, they are positively-charged. Because opposites attract, an object which is negatively-charged will attract another object which is positively-charged and vice versa.
when rubbed with hair, ruler acquires some charge due to static electricity...becomes charged body and attracts tiny pieces of paper towards it.
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.
paper sticking to a charged CD water attracted to an ebonite rod
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
A glass rod that is charged usually attracts the small bits of paper placed near it because it is usually electrostatically charged.

What I personally would do is tear a strip from a sheet of nose- or toilet-tissue, hang it next to the object under test but not touching it, and see if the paper is attracted to the object. I call it the 'poor man's gold leaf'.

If you rub an acetate rod with a cloth electrons are transferred from the rod to the cloth and the rod becomes negatively charged and the cloth becomes positively charged.

Paper Clips are made of usually made of steal or iron, which are magnetic materials, so they are attracted to magnets
The The molecules in the paper will orient themselves so that the positively charged sides point towards the rod and the negatively charged sides point away. Since the electrical forces decreases with increasing distance the nearer positive charges experience a stronger force than the more distant negative charges. As a result, the net force will be one of attraction.
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.
opposite electric charge
The glass rod aquires static electricity.the paper bits are negatively charged and the glass rod is positively charged.when it battracts the paper ,the both aquire like charges due to which they both are repelled.
