Which among the curves shown in figure cannot possibly represent electrostatic field lines ?

Text Solution

Verified by Experts

(a) Figure (a) is wrong because, all electric field lines are not locally perpendicular on the charged surface.
(b) Figure (b) is wrong because, electric field lines cannot emanate (start) from negative charge.
(c) Figure (c) is correct because, it does satisfy all the properties of electric field lines.
(d) Figure (d) is wrong because, electric field lines cannot intersect.
(e) Figure (e) is wrong because, electrostatic field lines cannot form closed loops and they cannot end up in a finite distance.
