Question

Define electric lines of force and its property?​

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

Explanation:

The properties of electric lines of force are:

i) Lines of force start from positive charge and terminate at negative charge.

ii) Lines of force never intersect.

iii) The tangent to a line of force at any point gives the direction of the electric field at that point.

iv) The number of lines per unit area, through a plane at right angles to the lines is proportional to the magnitude of E. That is, when the lines of force are close together, E is large and where they are far apart, E is small.

v) Each unit positive charge gives rise to
