What are the conditions if net electric flux through a surface is zero?
Gauss’s law tells us that the electric flux through a closed surface is proportional to the net charge enclosed by the surface. Thus, the electric flux through the closed surface is zero only when the net charge enclosed by the surface is zero.
Why is the flux through a closed surface zero?
If there is no net charge within a closed surface, every field line directed into the surface continues through the interior and is directed outward elsewhere on the surface. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero.
What is the electric flux through out of the surface of the box?
The electric flux through a surface describes the number of electric field lines that cross that surface. Mathematically, it is defined as the surface integral of the electric field through that surface. Hence, for a closed surface, the electric flux can be computed without evaluating any integrals.
When electric flux through a closed surface is not zero?
No, it is usually not zero. It is zero only if there is no electric charge enclosed in the closed surface. In simple math: Electric flux of the closed surface = Charge / permittivity.
What is the net electric flux through the closed surface that surrounds the conductor?
The net electric flux through a closed surface that surrounds no charge is zero.
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 is the net electric flux through the cube?
zero
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. The magnitude of the flux through rectangle BCKF is equal to the magnitudes of the flux through both the top and bottom faces.
Is the net electric flux through a closed surface is zero then we can infer?
In a closed surface, if the net electric flux is zero, then the net electric charge will be also zero. Since electric flux is defined as the rate of flow of electric field in a closed area and if the electric flux is zero, the overall electric charge within the closed boundary will be also zero.
What is the total electric flux through a closed surface containing a 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 do you calculate net flux?
The net flux is Φnet=E0A−E0A+0+0+0+0=0. The net flux of a uniform electric field through a closed surface is zero. A uniform electric field →E of magnitude 10 N/C is directed parallel to the yz-plane at 30o above the xy-plane, as shown in Figure 6.2.
What is the net outward flux of a box?
(b)The amount of net flux through a body depends on the net charge contained in a body. If net flux outwards flux the surface of the box is zero, then it can be inferred that there is no net charge inside the body. The body may have equal amount of positive and negative charges. Hence, net outward flux is zero.
What will happen if net flux is zero?
If net flux is zero, then it can be inferred that net charge inside the body is zero. The body may have equal amount of positive and negative charges. Video Explanation Was this answer helpful?
Does net flux depend on net charge inside the body?
Ans: No. The net flux entering out through a body depends on the net charge contained in the body. If the net flux is given to be zero, then it can be inferred that the net charge inside the body is zero.
What does net flux piercing out through a body depend on?
(b) No. Net flux piercing out through a body depends on the net charge contained in the body. If net flux is zero, then it can be inferred that net charge inside the body is zero. The body may have equal amount of positive and negative charges. Video Explanation
