- Electric charge: It is an intrinsic property of the elementary particles of matter which gives rise to electric force between various objects.
- It is a scalar quantity.
- SI unit of electric charge is coulomb (C).
- The total charge on the body is always an integral multiple of a basic quantum of charge i.e. q = ne
Where n = integer
EXPLANATION:
If a system has n charges like \({q_1},{q_2},{q_3},...{q_n}\).
- Then their total charge will be sum of all charges i.e.
\(\Rightarrow \left( {{q_1} + {q_2} + {q_3} + \ldots {q_n}} \right)\)
- This is called a principle of superposition of charges. Therefore statement 1 correct.
- It is the property of charges that is, like charges repel each other whereas unlike charges attract each other. Therefore statement 2 is incorrect and statement 3 is correct.
