Two electric field lines ______
A. Always intersect each other
B. Never intersect
C. May intersect sometimes
D. Are always perpendicular to each other
Answer:B
Two electric field lines ______
A. Always intersect each other B. Never intersect C. May intersect sometimes D. Are always perpendicular to each other
Explanation: We know that the electric field at a point is directed towards the tangent of electric field lines at that point. Now if two field lines intersect at a point, two tangents can be drawn at that point. That means at a particular point there would be two separate directions of the electric field which is impossible. So, we can conclude that two electric field lines never intersect each other.
