If two lines of force intersect each other at a point , then electric field at that point will have two direction . This cannot be true. Hence two lines of force can never intersect each other .
Can two electric lines of force ever intersect explain?
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.
Can two lines of force cross?
Field lines cannot cross. If two lines did cross, then the force on a charge would have two directions, which is impossible.
Why do two lines never intersect each other?
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.
Why two electric lines of force never intersect each other can two equipotential surface intersect?
They can’t intersect each other because two different equipotential surface have different electric potential, so if they intersect then the point point of intersection will have two different potential at the same point which is not possible.
What are electric lines of forces?
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 are electric lines of force write its properties?
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.
Why is a line of force so named?
The direction of force is along the tangent for a positive magnetic charge (north pole) and opposite for a negative magnetic charge (south pole). This explains why the alternate term for field lines “lines of force” is named in that way.
Who discovered fields?
Fields began to take on an existence of their own with the development of electromagnetism in the 19th century. Michael Faraday coined the English term “field” in 1845. He introduced fields as properties of space (even when it is devoid of matter) having physical effects.
What are the rules concerning the lines 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.
At what angle do two electric field lines intersect each other?
There would be two directions of electric field intensity at the same point it at the point of intersection it two electric lines of force intersect each other which is not possible. Hence no two electric field lines can intersect each other.
Why can electric fields never 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.
Why can’t two field lines from the same field/cross one another?
No, two field lines cannot intersect each other as if they intersect there will two direction of electric field at the same point which is not possible . Therefore two field lines cannot cross each other.
Why are two lines of force never found to intersect each other 10?
Reason – The two magnetic field lines do not intersect each other because if they do, it means at the point of intersecting, the compass needle is showing two different directions, which are not possible.
Why can’t 2 equipotential surfaces intersect?
They cannot intersect each other because two different equipotential surfaces have different electric potential. … Now the electric field is always perpendicular to the equipotential surface. If they are not perpendicular there will be two components which can cause charge to move along the surface.
Do electric lines of force have physical existence?
Each electric lines of force is conceptually imagined it does not have any physical existence. Total number of lines of force emanated from a charge body is equal to the charge of the body measured in Coulomb. … No lines of force can exists inside the conductor.
