Question -
Answer -
(a) The field lines showed in(a) do not represent electrostatic field lines because field lines must benormal to the surface of the conductor.
(b) The field lines showed in(b) do not represent electrostatic field lines because the field lines cannotemerge from a negative charge and cannot terminate at a positive charge.
(c) The field lines showed in(c) represent electrostatic field lines. This is because the field lines emergefrom the positive charges and repel each other.
(d) The field lines showed in(d) do not represent electrostatic field lines because the field lines shouldnot intersect each other.
(e) The field lines showed in(e) do not represent electrostatic field lines because closed loops are notformed in the area between the field lines.
