Question
Which among the curves shown in figure cannot possibly represent electrostatic field lines?
✓

Answer

  1. Field lines are wrongly drawn because electric field lines must be normal to the surface of the conductor at each point.
  2. Field lines are wrongly drawn because field lines cannot start from a negative charge.
  3. Field lines are correctly drawn, because they are originating from a positive charge.
  4. Field lines are wrongly drawn as the field lines cannot intersect.
  5. Field lines are wrongly drawn because they cannot form closed loops.
