Question

Which among the curves shown in Fig. 1.35 cannot possiblyrepresent electrostatic field lines?

Answer 1

a)

The electrostatic field lines are always normal to the surface of conductor. The given figure does not represent the electrostatic field lines because the field lines are not perpendicular to the surface of conductor.

b)

The electrostatic field lines are always emerge from a positive charge and finish on the negative charge. The given figure does not represent the field lines because they are emerging from the negative charge and end on the positive charge.

c)

Every individual field lines are always repelling each other. Also the electrostatic field lines are always emerge from a positive charge and finish on the negative charge. Thus, the field lines shown in given figure is represents the electrostatic field lines.

d)

No individual electrostatic field lines could intersect each other. The field lines shown in given figure are intersecting and that’s why does not represent the electrostatic field lines.

e)

The given figure does not represent the electrostatic field lines because there is no closed loop between the area of electrostatic field lines.
