Which of the following is true for electric charges?

The correct answer is option 4) i.e. All of the above

CONCEPT:

• Electric charge is a fundamental property of matter that causes the matter to experience a force when kept in electric and magnetic fields.
  • There are two types of charges possessed by matter - negative charge and positive charge.
  • The matter that is neither positive nor negative is said to be neutral.
  • The electric charge of the matter comes from the charge carried by electrons and protons at the atomic level.
  • The SI unit of electric charge is coulomb (C).
• Basic properties of electric charges:
  • ​Additivity of electric charge: The total charge of a system is obtained from the algebraic sum of the constituent charges.
  • Conservation of electric charge: Electric charges obey the law of conservation of charges. According to the principle of conservation of charges, the charges are neither created nor destroyed; they are only transferred from one body to the other. 

  • Quantization of electric charge: According to the principle of quantization of electric charge, all the charges are integral multiples of the charge of a fundamental quantity. An electron or a proton is a fundamentally charged quantity.

    • The charge possessed by a system, Q = ne

​Where n is the number of fundamental quantities and e is the charge of the fundamental quantity.

EXPLANATION:

• All the given statements are the basic properties of electric charges. Hence, they all are true.
