Correct Answer - Option 3 : Only c is correct

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:

• To positively charged a body we need to take out some electrons from the body.
• So to charge a body with a positive charge the number of protons will not change, so the atomic number does not change.
• A charge is always associated with mass.
• Since to create a positive charge, some electrons are taken out from the body so its mass will decrease.
• So only statement c is correct. Hence, option 3 is correct.
