What is the total electric flux coming out from a closed surface enclosing a stationary unit positive charge in air?

The total electric flux linked with the closed surface is $dfrac{1}{{{varepsilon _0}}}$ times of the charge enclosed by the closed surface. This law is known as Gauss law. By using this law, the question can be solved.

What is the flux coming out of a closed 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.

What will be the total flux of a closed surface when a charge is placed outside the surface?

(a) The electric flux through a closed surface due to a charge outside that surface is zero. (b) Charges are enclosed, but because the net charge included is zero, the net flux through the closed surface is also zero.

How much electric flux emerges out from a closed surface enclosing a charge Q?

According to gauss’s law, total electric flux through a closed surface enclosing a charge is 1/ϵ0 times the magnitude of the charge enclosed.

How do you find electric flux through A closed 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.

What is meant by electric flux through A surface?

Electric Flux through a surface is defined as the surface integral of the electric field lines passing normally through the surface. ϕ=∫E . dS. According to gauss’s law, total electric flux through a closed surface equals the net charge enclosed in the surface divided by the permittivitty.

What does it mean if the electric flux through a closed surface is negative?

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. Field lines directed into a closed surface are considered negative; those directed out of a closed surface are positive. …

What is the total electric flux through a closed surface containing 2.0 ΜC charge?

What is the total electric flux through a closed surface containing a 2.0 μC charge? Φ = q ε 0 = 2 ⋅ 1 0 − 6 8.85 ⋅ 1 0 − 12 = 0.23 M W b .

How much is the electric flux through a closed surface?

The net flux through a closed surface surrounding zero net charge is zero.

Is a positive charge is displaced against the electric field in which it was situated then?

if charge is positive than force is directed to the direction of field while if charge is negative force acts on it in the opposite direction of a field . so, if a positive charge is displaced against the electric field in which it was situated then work will be done by the electric field on the charge.

What is the flux through a cube of side A If a point charge of Q is at one of its corner?

If the charge ‘q ‘is placed at one of the corners of the cube, it will be divided into 8 such cubes. Therefore, electric flux through the one cube is the eighth part of [dfrac{q}{{{varepsilon _circ }}}].

What is the electric flux through a closed surface enclosing an electric dipole?

“The net electric flux through any hypothetical closed surface is equal to 1ε0 times the net charge within that closed surface.” So, the net charge in the above question is zero. Electron dipole is a positive and negative charge of equal magnitude at a specific distance.

What is the electric flux through the upper face of the box?

The electric flux through the top face (FGHK) is positive, because the electric field and the normal are in the same direction. The electric flux through the other faces is zero, since the electric field is perpendicular to the normal vectors of those faces.

What will be the electric flux through the closed surface of the size is doubled?

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