Correct Answer - Option 3 : The body has lost some electrons

CONCEPT:

Electric Charge

  • It is defined as the intrinsic property of certain fundamental particles like electrons, proton, etc, due to which they produce electric and magnetic effects.
  • Types of electric charge
    1. ​Positive charge: A body having a deficiency of electrons.
    2. ​Negative charge: A body having an excess of electrons.
  • Properties of electric charge
    • Like charges repel and unlike charges attract each other.
    • A charge is a scalar quantity.
    • A charge is always quantized.
    • A charge will always remain conserved.
    • A charge is always associated with mass.
    • The unit of charge is the coulomb.

⇒ 1 coulomb= charge on 625×1016 electrons

EXPLANATION:

  • ​Positive charge: A body having a deficiency of electrons.
  • We know that the proton is present in the nucleus so, we can't add or remove protons in the element but we can add or remove electrons from the element.
  • So the body can be positively charged by removing electrons and negatively charged by adding electrons.
  • A charge cannot be generated by adding or removing protons. Hence, option 3 is correct.
