## What is electric line of force?

An electric line of force is an imaginary line that is a continuous line or curve that we draw in an electric field such that tangent to it at any point gives the direction of the electric lines of force at that point.

## What are electric lines of force answer?

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 is electric lines of force write the properties of electric lines of force?

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.

## 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 is electric line of force and its property?

An electric line of force is a smooth curve drawn in the electric field so that the tangent at any point on the curve gives the direction of electric field at that point. Properties: Lines of force are continuous curves, which start from a positive charge and end on a negative charge.

## What is electric line of force and its importance?

What is its importance? An electric line of force is an imaginary straight or curved path along which a small positive test charge is supposed to move when free to do so. The tangent at a point on an electric line of force gives the direction of the resultant electric field at that point.

## What are electric lines of force state any four characteristics of lines of force?

1) The electric lines of force start from a positive charge and ends on a negative charge. 2) The electric lines of force always enter or leave the charged surface normally. 3) Electric lines of force can never intersect each other. 4) The electric lines of force cannot pass through a conductor.

## What is line of force 10th?

The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. They show the direction and strength of magnetic field. If magnetic field lines are very close to each other in a particular region,then the strength of magnetic field in that region,is very large.

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

Properties of lines of force :-

1-Lines of force originate from a positive charge and terminate to a negative charge. 2-The tangent to theline of force indicates the direction of the electricfield and electric force.

## What is electric dipole Class 12?

The electric dipole is a pair of two equal and opposite charges, +q and −q are separated by a very small distance. … The electric dipole moment of the electric dipole is defined as the product of the magnitude of one of the charges of the dipole and the separation distance between them.

## What is electric field lines are continuous?

An electrostatic field line is a continuous curve because a charge experiences a continuous force when placed in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump fom one point to another.

## Why the electric lines of force are not continuous?

“Every line of force in an electrostatic field originates from a positive charge at one end and terminates on a negative charge at other and they are discontinuous curves.

## Why electric lines of force are called continuous and not closed in nature explain?

The main reason behind the electrostatic field lines not forming a closed loop is that the no electric field line exists inside the charged body. Therefore, we say electrostatic field lines never form closed loops.
