Best answer: Which surface A or B has a larger electric flux through it?

The electric flux is directly proportional to the value of the enclosed charge. Gaussian surface B encloses more charge (2Q) than Gaussian surface A (Q). Therefore, surface B has a larger electric flux than surface A.

In which case 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.

What is the electric flux through each surface?

The flux Φ of the electric field →E through any closed surface S (a Gaussian surface) is equal to the net charge enclosed (qenc) divided by the permittivity of free space (ϵ0): Φ=∮S→E⋅ˆndA=qencϵ0. To use Gauss’s law effectively, you must have a clear understanding of what each term in the equation represents.

Does electric flux depend on surface area?

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 two features about A surface are important when calculating the electric flux through the surface?

Equation of Electric Flux

Strength of the Electric Field. Area of the Surface. Orientation of the surface with respect to the lines of force.

When electric flux will be minimum and maximum?

a. If the planar surface is perpendicular to the electric field vector, the maximum flux would be obtained. b. If the planar surface were parallel to the electric field vector, the minimum flux would be obtained.

How do you find flux on a surface?

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 Gaussian surface has the greatest electric flux?

The electric flux is directly proportional to the value of the enclosed charge. Gaussian surface B encloses more charge (2Q) than Gaussian surface A (Q). Therefore, surface B has a larger electric flux than surface A.

What is the electric flux through the cube?

The net electric flux through the cube is the sum of fluxes through the six faces. Here, the net flux through the cube is equal to zero. … Therefore, quite generally, electric flux through a closed surface is zero if there are no sources of electric field, whether positive or negative charges, inside the enclosed volume.

What is the electric flux through one face of the cube?

The flux through the surface of this cube is just q/ϵ0 by Gauss’s Law since it is a closed surface containing the charge. Now imagine dividing each face of this larger cube into four squares of side length ℓ.

Does electric flux depend on medium?

Yes, the medium affect the electric flux. Vacuum permitivity relates the relative effect against that of an ideal vacuum.

What will be the electric flux through a closed surface if its size is double?

d→S=qε0 ϕE∝∫dS ∴ Flux will also doubled, ie, 2ϕ .

What does flux depend on?

Flux is the amount of “something” (electric field, bananas, whatever you want) passing through a surface. The total flux depends on strength of the field, the size of the surface it passes through, and their orientation.

Which surface is more appropriate for calculating the electric flux?

Which surface is more appropriate for calculating the electric flux? ◦ Cylindrical surface is more appropriate.

What is the flux through a surface if surface is parallel to the lines of force?

If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero. If the surface is rotated with respect to the electric field, as in the middle panel, then the flux through the surface is between zero and the maximal value.

What is flux in electric field?

electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. … The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero.
