Question

Positive charge can be generated on a body by:
1. Adding proton
2. Removing electron
3. Adding electron
4. By adding proton or removing electron

Answer 1

Correct Answer - Option 2 : Removing electron

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 2 is correct.
