MCQ
What do you understand by the static or frictional electricity?
  • A
    Discarging of two bodies on rubbing them together is called static or frictional electricity.
  • ✓
    Charging of two bodies on rubbing them together is called static or frictional electricity.
  • C
    Electricity which is static is called static or frictional electricity.
  • D
    Electricity on high friction bodies is called static or frictional electricity.
✓

Answer

Correct option: B.
Charging of two bodies on rubbing them together is called static or frictional electricity.

Static electricity is produced when a suitable combination of substances $($e.g., glass rod and silk, ebonite rod and cat's skin, sealing wax and wool$)$ are rubbed together and get electrified due to friction.
