Correct Answer - Option 1 : Charged

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:

  • Around 600 BC the Thales of Miletus, Greece discovered that when an amber rubbed with wool or silk cloth, it attracts light objects.
  • Similarly, many such pairs of materials are known which on rubbing could attract light objects like straw, pith balls, and bits of paper. This phenomenon occurs because when a body is rubbed with another body, it will get charged. Hence, option 1 is correct.
  • A strongly magnetic substance can be magnetized by keeping it in an external strong magnetic field.
