# Net Electric Flux & Enclosed Objects

• Gear300
In summary, net electric flux is a measure of the total amount of electric field passing through a given surface. It is calculated by taking the integral of the dot product of the electric field and the surface area over a given closed surface. An enclosed object is a closed surface that surrounds a charge or group of charges, and the net electric flux through this surface is influenced by the amount and distribution of charges inside. This concept is related to Gauss's Law, which states that the net electric flux through a closed surface is equal to the charge enclosed divided by the permittivity of free space. If the enclosed charge is zero, the net electric flux through the closed surface will also be zero.

If I were to take an enclosed object, like a rock, container, etc... and put it within an electric field any distance away from the source charge (so long as the source charge isn't inside the object)...would the net electric flux always be zero?

Yes! because as much flux entering the object is outgoing... the net flux entering or outgoing an object is depended to the net charges inside the object which in this case is zero.

Ok. Thanks.

## 1. What is net electric flux?

Net electric flux is a measure of the total amount of electric field passing through a given surface. It is defined as the dot product of the electric field and the surface area, and is measured in units of volts.

## 2. How is net electric flux calculated?

Net electric flux is calculated by taking the integral of the dot product of the electric field and the surface area over a given closed surface. This integral is known as the electric flux integral and is represented by the symbol ΦE.

## 3. What is an enclosed object in relation to net electric flux?

An enclosed object in the context of net electric flux is a closed surface that surrounds a charge or a group of charges. The net electric flux through this surface is influenced by the amount and distribution of charges inside the surface.

## 4. How does net electric flux relate to Gauss's Law?

Gauss's Law states that the net electric flux through a closed surface is equal to the charge enclosed by that surface divided by the permittivity of free space (ε0). This relationship is expressed in the equation ΦE = Q/ε0, where Q is the charge enclosed by the surface.

## 5. Can the net electric flux through a closed surface ever be zero?

Yes, the net electric flux through a closed surface can be zero if the enclosed charge is also zero. This is because the electric field is proportional to the charge, so if there is no charge present, there will be no electric field passing through the surface.
