Define an electric line of force.
An electric line of force
is an imaginary continuous line or curve drawn in an electric field such that
tangent to it at any point gives the direction of the electric force at that
point. the direction of a line of force is the direction along which a small
free positive charge will move along the line. It is always directed from
positive charge to negative charge.
Some of its important
characteristics are
1.
Electric lines of force contract longitudinally.
2.
They expand laterally.
3.
Two electric lines of force cannot intersect each other.
4.
Two electric lines of force proceeding in the same direction
repel each other.
5.
Two electric lines of force proceeding in the opposite direction
attract each other.
6.
The lines of force are imaginary but the field it represents as
real.
7.
There are no lines of force inside the conductor.
