Question
Select the correct statements about electric field lines.
I. Two electric field lines can never cross each other.
II. They always start from a positive charge and end at a negative charge.
III. Electric field lines don’t form closed loops.
- I, II, and III
- I and II
- II and III
- I and III
Hint:
An electric field (sometimes E-field) is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them
The correct answer is: I and III
i)Electric field lines originate from positive charge and terminate at negative charge .
(ii) more electric field lines more strength of electric field
(iii) They are radial for point charge.
(iv)They have not any physical existance
(v) 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.
