# What do electric lines of force represent Class 12?

Contents

Electric lines of force represents the direction of electric field. Electric lines of force can be defined as a way or path, it may be straight or curved, so that the tangent at any point to it gives the direction of the electric field intensity at that point.

## What is an electric lines of force Class 12?

An electric line of force is an imaginary curve drawn in such a way that tangent to this curve at any point gives the direction of the electric field at that point. It can be a path with maybe a curve or a straight line.

## What are electric lines of force give their important properties Class 12?

The field lines never intersect each other. The field lines are perpendicular to the surface of the charge. The magnitude of charge and the number of field lines, both are proportional to each other. The start point of the field lines is at the positive charge and end at the negative charge.

## What do you mean by electric lines of force write four properties?

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.

## What do electric lines of force represent?

Electric lines of force represents the direction of electric field. Electric lines of force can be defined as a way or path, it may be straight or curved, so that the tangent at any point to it gives the direction of the electric field intensity at that point.

## What are electric lines of forces?

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.

## What is the importance of electric field lines?

Electric field lines reveal information about the direction (and the strength) of an electric field within a region of space. If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location.

## Why electric lines of force are continuous?

(a) An electrostatic field line is a continuous curve because a charge experiences a continuous force when traced in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump from one point to the other. … Hence, two field lines never cross each other.

## What do you mean by a line of force Why is it so named?

In Physics, lines of force is the path followed by an electric charge. … In physics, lines of force is an imaginary line that represents a field of force, such as an electric or magnetic field. If we draw a tangent at any point on the lines of force gives the direction of the field vector at that point.

## Which physical quantity is represented by electric lines of force?

The physical quantity obtained by the line integral of the electric field is potential and its unit is \$JC^{ -1}\$. Potential is the energy per unit charge. The electric field is the region in which a charge applies force of attraction or repulsion on another charge.
