The Electric Line Of Force

For positive charge the electric lines of force move away from the centre of the charge.

The electric line of force.

The electric field for positive and negative charges are shown below. A positive point charge free to move may or may not follow the line of force. Line of force in physics path followed by an electric charge free to move in an electric field or a mass free to move in a gravitational field or generally any appropriate test particle in a given force field. The tangent to the line of force at a point in an electric field gives the direction of intensity.

Line of force synonyms line of force pronunciation line of force translation english dictionary definition of line of force. Define line of force. A second rule for drawing electric field lines involves drawing the lines of force perpendicular to the surfaces of objects at the locations where the lines connect to object s surfaces. It gives direction of force and hence acceleration which a positive charge will experience there and not the direction of motion.

Electric force exists between charges as described by coulomb s law. More abstractly lines of force are lines in any such force field the tangent of which at any point gives the field direction at that point and the density of which gives the. Line density in an electric field line pattern reveals information about the strength or magnitude of an electric field. Consider a unit charge q placed in a vacuum.

The line along which the unit positive charge moves towards the said negative charge is defined as an electric line of force. A line of charge with q off the end. An imaginary line drawn so that each segment of the line is parallel to the direction of the electric field or of the electric displacement at that point and the density of the set of lines is proportional to the electric field or electrical displacement. Now let us take a positive charge of q coulomb.

General physics an imaginary line representing a field of force such as an electric or magnetic field such that the tangent at any point is the direction of the field vector at that point. The electric field is represented by the imaginary lines of force. Written by willy mcallister. For the positive charge the line of force come out of the charge and for negative charge the line of force will move towards the charge.

Electric lines of force are also called as electric field lines. We place a unit positive charge at a point in the. If we placed the unit positive charge anywhere else in the field the line of force was created along that new point. The concept of electric lines of forces was introduced by michael faraday in 1837.
