Which of the following statements are true for electric field lines?
1) electric field lines can never intersect.
2) electric field lines are continuous; they do not have a beginning or an ending.
3) electric field lines point away from positive charges and toward negative charges.
4) electric field lines are close together in regions of space where the magnitude the electric field is weak and are father apart where it is strong.
5) at every point in space, the electric field vector at that point is tangent to the electric field line through that point.

Explanation:

Statement 1 is true i.e. Electric field lines can never intersect otherwise there would be two direction of Electric field at that point.

Statement 2 is false because electric field lines start from a positive charge and ends on negative charge.

Statement 3 is true

Statement 4 is incorrect because Electric field lines are closer where the field is strong and wider where it is weak.

Statement 5 is correct                  

the answer is b
