1. The direction of Electric field intensity at a point can be calculated by drawing the tangent to the line of force at that point.
2. Due to the attraction between unlike charges, the electric lines of force reduce longitudinally.
3. Due to the repulsion between the like charges, the line of force applies a lateral pressure.
4. Electric lines of forces never intersect each other. This point can be cleared easily through a figure.
Let us suppose that two lines intersect at a point. So draw tangents to that point along the lines of force. You will see that their will be two directions of the electric field intensity at a single point, which is not possible.
5. All the components of electric field intensity are perpendicular to the outermost layer of the conductor.
