Question
Select the correct statements about electric field lines.
I. Two electric field lines can cross each other.
II. They start from a positive charge and may end at a negative charge.
III. Electric field lines form closed loops.
- I, II, and III
- I and II
- II and III
- I and III
Hint:
Since electric field lines originate and terminate on charges of opposite polarity,
The correct answer is: II and III
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.
