Explanation of Solution
Introduction:
Field lines represent a uniform electric field penetrating a plane of the area perpendicular to the field. The electric field is a vector field around a charged particle. It represents the force that other charged particles would feel if placed near the particle creating the electric field.
If the charge is positive, field lines points radially away from the rod; if the charge is negative, field lines points radially towards the rod. As the charge is negative, the field lines points radially towards the rod.
