Which of the following statements about electric field lines due to static charges are true? (select all that apply.)

a. electric field lines can never cross each other.
b. electric field lines point from negative charges toward positive charges.
c. static charges can create closed loop electric field lines that do not begin or end on a charge.
d. wider spacing between electric field lines indicates a lower magnitude of electric field.

a. Electric field lines can never cross each other.

d. Wider spacing between electric field lines indicates a lower magnitude of electric field.

Explanation:

a. The electric field lines cannot be crossed, since this would mean that there would be more than one electric field vector for the same point at the place where the crossing occurs.

d. The space between the field lines is inversely proportional to the intensity of the electric field.

"a" and "d" are correct

Explanation:

(a) Field lines can never cross. Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would imply that the electric field was pointing in two different directions at a single point.

(b) Wider spacing between electric field lines indicates a lower magnitude of electric field.
