This means flux lines per unit area is always same, irrespective of distance. The electric field is thus constant and same anywhere in its effective area. This field remains constant up to a second infinite conducting plane parallel to the first plate from which the lines emanate.
Does electric flux depends on distance?
The flux doesn’t depend on the distance r. We would get the same result no matter the size of the closed surface around the point charge.
Is electric field independent of distance?
Example: Electric field near a plane of charge. … The result will show the electric field near an infinite plane of charge is independent of the distance away from the plane (the field does not fall off).
On which factors electric flux depends?
The numerical value of the electric flux depends on the magnitudes of the electric field and the area, as well as the relative orientation of the area with respect to the direction of the electric field.
Why does electric field not depend on distance?
But once, the charged object is an infinite plane sheet, the field lines can’t diverge, because if they do, they would be intersecting each other ( A violation of the laws of physics). And since, the field lines are parallel, they are uniform, which means, they would not depend on the distance from the plane.
What is the flux not depend on?
As per the Guess theorem in electrostatics, electric flux does not depend on the shape or size of the surface. The electric flux depends only on the charge enclosed by the surface.
What is electric flux equal to?
The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.
Which is independent of distance?
The electric field is independent of distance ONLY for an infinite sheet of uniform charge distribution. (And also for the trivial case of a volume that has zero electric field throughout its volume.)
Is electric flux a vector quantity?
Electric flux is a scalar quantity because it is the dot product of two vector quantities, the electric field, and the perpendicular differential area.
Why electric field due to infinite sheet is independent of distance?
Why electric field is independent of distance
Since the lines are parallel, the number of electric lines of force through a certain area does not change in the case of plane sheet. So electric field is also independent of the distance.
When electric flux is maximum?
The electric flux of a surface is maximum when the area vector is parallel to the direction of the electric field. The electric flux is the total number of lines of force passing through a surface.
At what angle electric flux is maximum?
Therefore flux will be the maximum if the angle is 0 degrees.
What is the use of electric flux?
They are used in circuitry for temporary energy storage, as part of filters. They are used as bypass paths for oscillating components of signals in circuitry. Electric flux is also used in photocopying machines, in cleaning applications like house-hold air purifiers and industrial electrostatic precipitators.
Does the electric field near a large sheet of charge depend on the distance from the sheet?
By symmetry,the magnitude of electric field E at all the points of infinite plane sheet of charge on either sides end caps is same and along the outward drawn normal,for positively charged sheet. … Thus, the field is uniform and does not depend on the distance from the plane sheet of charge.
How does the electric field due to an infinite line of charge depend on the distance to the line?
if you have a point r distance above the end of the line, as the distance increases the electric field would decrease because the “ends” behave like point charges.
Why is electric field independent of test charge?
Both the magnitude and direction of the Coulomb force field depend on Q and the test charge q. … The electric field is thus seen to depend only on the charge Q and the distance r; it is completely independent of the test charge q.
