Question

A comb rubbed with hair attracts small pieces of paper?Give reason

Answer 1

Most of us have seen the magical event when paper strips start ‘dancing’ and flying when a comb rubbed on clothes or hair is brought near them.
This is because the comb gets charged when it is rubbed. All the objects that we see around us are made of atoms, which are small uncharged particles. It consists of a positive centre made of positively charged protons and neutral neutrons, and negatively charged electrons orbiting around it almost like planets orbit around the sun.

These atoms contain equal number of protons and electrons so they are uncharged.
So the surface of any object made of atoms has electrons, which are negatively charged.
When the comb is rubbed against the cloth the electrons move between the two, and the comb gets charged.
