Question: Why electric field lines Cannot have sudden breaks?

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.

Can electric field lines be broken?

(i) An electrostatic field line is a continuous curve. That is, a field line cannot have sudden breaks.

Why electric field lines I can never intersect one another II Cannot for closed loops Sometimes III Cannot have break in between?

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.

Can electric lines of force be discontinuous?

1. Electric lines of forces start from a positive charge and end in negative charge. … Electric lines of forces are continuous curves if there is no conductor. And the lines of forces are discontinuous for the conductor.

Why can’t electric field lines cross?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

Where is the electric field the strongest?

The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.

Are electric field lines straight?

In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.

Why electric field inside a conductor is zero?

Due to a large number of electrons, the force of repulsion acting in between them is also very high. Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.

Why do the electric field lines never cross each other Class 12?

And due to two different tangents there are two different directions of electric field at that point. It is not possible that there are two directions of electric field at the same point. Hence, electric field lines never intersect each other is true and this is also a property of electric field lines.

Why must electrostatic field be normal to the surface?

Electric field is defined as the gradient of potential and the surface of a conductor has a constant potential. Therefore, there is no field along the surface of the conductor and hence the electrostatic field at the surface of a charged conductor should be Normal to the surface at every point.

What are electric line of force?

The electric lines of force that represent the field of a positive electric charge in space consist of a family of straight lines radiating uniformly in all directions from the charge where they originate. A second positive charge placed in the field would travel radially away from the first charge.

What is are electric line of force what are its 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.

Can electric field lines intersect in free space?

Every single location in space has its own electric field strength and direction associated with it. Consequently, the lines representing the field cannot cross each other at any given location in space.

How do you calculate the electric field?

In vector calculus notation, the electric field is given by the negative of the gradient of the electric potential, E = −grad V. This expression specifies how the electric field is calculated at a given point. Since the field is a vector, it has both a direction and magnitude.

How do electric field lines indicate the strength of an electric field? the space that surrounds electrically charged particles. The closer you get tp a charge, the stronger it gets. … The repulsion of the like charges creates a space (Gap X) between their electric fields.
