Properties Of Electric Field Lines

#) Properties Of Electric Field Lines:

*) The electric lines of force are imaginary lines.

*) A unit positive charge placed in the electric field tends to follow a path along the field line if it is free to do so.

*) The electric lines of force emanate from a positive charge and terminate on a negative charge.

*) The tangent to an electric field line at any point gives the direction of the electric field at that point.

*) Electric lines of force are perpendicular to the surface of a positively or negatively charged body.

*) Electric lines of force contract lengthwise to represent attraction between two unlike charges.

*) Electric lines of force exert lateral (sideways) pressure to represent repulsion between two like charges.
