MCQ
Identify the WRONG statement in the case of electric field lines.
  • They do not pass through an insulator.
  • B
    They do not pass through a conductor.
  • C
    They start from a positive charge and end on a negative charge.
  • D
    They do not intersect each other.

Answer

Correct option: A.
They do not pass through an insulator.
(a) : Electric field lines passes only through insulator. Insulators are the materials that obstruct free flow of electrons from one particle of the element to another.
