Electrostatics

There are two kinds of charges; _____ and_____

Materials which do not conduct electricity are

called insulators

Rubber¸ plastic¸ glass and dry air are the examples

of conductors.

An atom is composed of protons and neutrons

Total amount of charge of a system remains

the same

Íf a neutral conducting object is brought into

contact with a negatively charged one¸ both will

be negatively charged.

Negative charges can move but positive charges

can not move

The force between the charged particles is called

electrostatic force.

The force due to unlike charges is called repulsive

force
