Question
Which of these is false about the electric field lines?
- The electric field lines originate from a positive charge and end in a negative charge.
- Two electric field lines never intersect each other.
- Electric field lines form closed loops.
- For a single charge, the electric field lines end at infinity.
Hint:
Since electric field lines originate and terminate on charges of opposite polarity,
The correct answer is: Electric field lines form closed loops.
- Since electric field lines originate and terminate on charges of opposite polarity, electric field lines can never form closed loops as to form a closed loop, the electric field lines must originate and end at the same charge.
