Which of the following correctly describe electric field lines? say/check all that apply a.) they never cross b.) field lines that are close together indicate a stronger electric field c.) they don't affect the charge that created them. d.) they begin on north poles and end on south poles.

-- Electric field lines DO never cross.  (A)

-- Electric field lines that are close together DO indicate a stronger electric field. (B)

-- Electric field lines DO not affect the charge that created them.  (C)

-- Electric field lines DON'T begin on north poles and end on south poles.  North and South "poles" are the way we talk about magnets, not electric charges.

Explanation:

The imaginary lines that shows the direction of electric field are called electric field lines. The direction of electric field lines are from positive charge to the negative charge.

Two electric field lines can never ever intersect, if they do so there would be two direction of electric field at that point, which is not possible.

If the electric field lines are very to each other, then it indicates the stronger electric field. The electric field lines is unaffected by the nature of charged particle that created them.

Hence, the correct options are :

(A) They never cross

(B) Field lines that are close together indicate a stronger electric field

(C) They don't affect the charge that created them.

c. magnitude and direction
