Which of the following curves shown below cannot possibly represent electrostatic field lines?

Explanation

(a) As electrostatic field lines start or end only at `90^(@)` to the surface of the conductor, therefore, Fig. cannot represent such lines.
(b) Electronstatic lines of force do not start from a negative charge. Therefore. Fig, also cannot represent such lines.
(c) Fig. represents electrostatic lines of force.
(d) As no two electrostic lines of force can intersect each other, therefore, Fig, cannot represent these lines.
(e) Fig. cannot represent electric lines of force as they never closed loops.
