What is an electric line of force give its four important properties?
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 are electric lines of force and their properties?
Properties of Electric Lines of Force
Each electric line of force originates from the positive charge and terminated to the negative charge. A tangent drawn at any point on an electric line of force indicates the direction of the electric field lines at that point in the field.
What are electric lines?
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 electric lines of force and its properties 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 is the importance of electric lines of force?
An electric line of force is the path along which a unit positive charge will move inside the electric field, if it is free to do so. The importance of electric line of force is that the tangent at any point to it gives the direction of electric field at that point.
What are properties of line 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.
What is an electric lines of force straight?
If the unit positive charge is free to move, that will move towards the charge – Q, along the straight line joining the center of unit positive charge and the center of said negative charge. The line along which the unit positive charge moves towards the said negative charge, is defined as an electric line of force.
