Yes, the electrostatic field line is a continuous curve because a unit charge always experiences a continuous force when it is placed in an electrostatic field.
Are electric field lines 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.
Are electric field lines curved?
An electric field line is, in general, a curve drawn in such a way that the tangent to it at each point is in the direction of the net field at that point.
Are electric field lines continuous curves in free space?
<br> R : Electric field lines start from negative charge and terminate at positive charge.
Does electric field have to be continuous?
Conventionally, electric field lines emerge out of a positive charge and sink up at the negative charge. That is because we take a ‘unit positive charge’ as a measure to define electric field. As far as the logic goes, electric field lines should always be continuous.
Why electric field lines is a continuous curve?
(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.
Why are electric field lines not closed curves?
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. … Therefore, we say electrostatic field lines never form closed loops.
Are electric field lines always straight lines?
Electric field lines are always straight. All electric potemtials are measured with respect to the negative terminal of the power supply.
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.
When electric field lines are curved the electric field at any point?
When electric field lines are curved, the electric field at any point is tangent to the field line at that point. Two nuclei each contain two protons and exert a force 4 N on each other.
Why electric field lines are continuous in charge free region?
The idea is that electric field lines can start on positive charges and finish on negative charges. In such a case electric field lines would be discontinuous. With no charges present the electric field lines must be continuous.
Are magnetic field lines continuous?
Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.
Why are field lines taken to be continuous curves without any breaks in a charge free region?
The electric field lines start on positive charges and finishes on negative charges. … However with no charges present the electric field lines must be continuous. Thus in a charge free region, electric field lines can be taken to continuous curves without any break.
Do field lines overlap?
The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.
What is the definition of electric field lines?
An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.
Does electric field lines form Closed Loop?
Hint: Electric field lines never form closed loops since electric field lines originate at one polarity of charge and end at the opposite polarity of charge.
