Draw electric field lines of simple charge distribution.

Explanation

The picture of field lines was invented by Faraday to develop an way to visualizing electric fields around charged configurations. Faraday called them lines of force.
Figures show the field lines around some simple charge configurations. As mentioned earlier, the field lines are in 3-dimensional space, though the figure shows them only in a plane.

Electric field lines for positive charge are shown in figure (a).
Electric field lines for negative charge are shown in figure (b).
Electric field lines for dipole are shown in figure (c).
