Question

When two bodies have similar charges are kept close to each other, then they will:
1. Repel each other
2. Attract each other
3. Neither attract nor repel
4. Can't say

Answer 1

Correct Answer - Option 1 : Repel each other

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:

• Like charges repel and unlike charges attract each other.
• So when two bodies have similar charges are kept close to each other, they will repel. Hence, option 1 is correct.
