What happens when the charge is outside the surface?

According to Gauss law, flux coming out of a surface is equal to 1/ε times the net charge enclosed by the surface. In this case, net charge enclosed is zero and hence flux through the surface is zero.

Is the net electric flux through a closed surface is zero then?

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 electric flux through a closed surrounding to charge?

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

At what condition electric flux is zero?

Yes, electric flux is zero when an electric field is perpendicular but not at a surface. It is zero when it is perpendicular to the area vector as E.S=EScos(90)=0.

Why is electric field is zero inside a charged conductor?

Electric field is zero inside a charged conductor. For a charged conductor, the charges will lie on the surface of the conductor.So, there will not be any charges inside the conductor. When there is no charge there will not be electric field.

Does zero electric flux imply zero electric field?

Zero flux does not imply zero field in general.

Why is electric flux negative?

Electric Flux is defined as dot product between Electric field and area vector (We always take outward normal). Flux is negative implies that E and ds are anti-parallel. If net charge present inside that hypothetical surface is negative, then flux is negative.

Can the electric flux be zero if there is no charge?

In the electromagnetic theory, Gauss’s law proves that the total electric flux through a closed surface is proportional to the electric charge inside the surface. So when there is no charge inside a close surface, we can say that the electric flux is zero. Can an electric field be zero if the electric force between two point charges is zero?

What is the electric flux in an electric filed?

The electric filed is a special type of a vector which has a non-zero divergence if there is some non-zero charge. The electric flux will be zero only if there is no charge enclosing that surface. However if you place an uncharged sphere in a uniform electric filed, the sphere develops induced charges.

What if the electric field inside a closed surface is zero?

If the flux of the electric… So if the electric field is zero everywhere, then the flux may be zero. if charge inside the closed surface is zero, then flux must be zero.

What is the electric field flux through a closed sphere?

So if you have a sphere(closed surface) and you put it in an uniform electric field, then the total flux is 0. However, the Gauss’s law states that the electric field flux through a closed surface equals the enclosed charge divided by the permitivity of free space.
