1.	Which among the following statements is true with regard to electric field lines?(a) Electric field lines always intersect(b) Electric field lines may or may not intersect(c) Electric field lines can be seen(d) Electric field lines never intersectThis question was posed to me during an interview.The doubt is from Electric Fields topic in portion Capacitance and Capacitors of Basic Electrical Engineering
Answer» CORRECT ANSWER is (d) Electric field LINES never intersect Explanation: Electric field lines can never intersect because tangent at any point on electric field lines represent the DIRECTION of electric field and if they intersect at a point it means that at that point there are two different directions for electric field which is not POSSIBLE.
