TYPE OF CHARGES There are two type of electric charges, positive charge (+) and negative charge(-) PROPERTIES OF ELECTRIC CHARGES Unlike charges, always attract each other. Positive charge kept near negative charge/ negative charge kept near positive charge, attract each other. Like charges always repel each other. Positive charge kept near positive charge / negative charge kept near negative charge, repel each other. PRESENCE OF CHARGE IN MATTER All the materials around as are generally known as matters (matter is anything that can occupy space and have mass). All the matters are made up of tiny building unites called atoms. Atoms are made up of some small subatomic particles – electrons, protons, neutrons. The centre part of the atom is known as nuclear , which contain protons and neutrons . Protons are positively charged particles and neutrons are chargeless particle (neutral). And electrons which are revolving around the nuclear of an atom in fixed orbits has negative charge.
