Question

What is physical significance of electric lines pf forces?

Answer 1

Answer:

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.

Answer 2

$\large \sf{Answer}$

An electric field is an elegant way of characterizing the electrical environment of a system of charges. The electric field at any point in space around a system of charges represents the force a unit positive test charge would experience if placed at that point.
