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 are electric lines of force explain?
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.
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.
What are electric field lines give their three important properties?
Electric field lines start from a positive charge and end at a negative charge, in case of a single charge, electric field lines end at infinity. In a charge-free region, electric field lines are continuous and smooth.
What are electric lines of force 11?
Electrical lines of force can be described as a way or path, it can be straight or curved so that the tangent gives the direction of the intensity of the electric field at that point at any point.
Is electric lines of force continuous or discontinuous?
Electric field lines are continuos curves. They start from a positively charged body and ends at a negatively charged body. No electric lines of force exist inside the charged body. Thus electrostatic field lines are continuous but do not form closed loops.
Why electric lines of force are called continuous and not closed in nature?
The test charge does not tend to return to its starting point so the field line doesn’t form a closed loop. … If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative.
Why do electric field lines never cross each other Class 12?
Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible.
