Can electric field lines be 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.
When electric line of force is straight?
Answer: 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.
Why can’t two electric lines of force intersect each other?
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.
Do electric lines of force really exist?
Electric lines of forces are imaginary lines it shows that if a point charge is put up somewhere than its direction of motion can be shown by it.
Are lines of force real?
There are no “real” lines of force. Fields lines are simply a mathematical construct used for visualization only. Only the allignment, i.e. direction, of the filings are measurable.
What are the properties of line of force?
- Lines of force originate from a positive charge and terminate to a negative charge.
- The tangent to theline of force indicates the direction of the electricfield and electric force.
- Electric lines of force are always normal to the surface of charged body.
- Two electric lines of force cannot intersect each other.
Are two magnets twice as strong as one?
Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.
