## What is the net flux through the cube of side 20 cm?

What is the net flux of the uniform electric field of question 1.15 through a cube of side 20 cm oriented so that its faces are parallel to the coordinate planes? The area of each face out of the six faces of the cube = 20 x 20 = **400 cm ^{2} = 4 x 10^{–}^{2} m^{2}.**

## How does electric flux due to a point charge?

How does the electric flux due to a point charge enclosed by a spherical Gaussian surface get affected when its radius is increased? … That is, on **increasing** the radius of the gaussian surface, charge q remains unchanged. So, flux through the gaussian surface will not be affected when its radius is increased.

## What is the area of the cube?

Explanation: The surface area of a cube **= 6a ^{2}** where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube. We have 96 = 6a

^{2}→ a

^{2}= 16, so that’s the area of one face of the cube.

## What is the net flux of uniform electric field?

If the electric field is uniform, the electric flux passing through a surface of vector area S is **ΦE=E⋅S=EScosθ Φ E = E ⋅ S = ES cos ** where E is the magnitude of the electric field (having units of V/m), S is the area of the surface, and θ is the angle between the electric field lines and the normal ( perpendicular ) …

## What is electric flux in simple words?

In electromagnetism, electric flux is **the measure of the electric field through a given surface**, although an electric field in itself cannot flow. It is a way of describing the electric field strength at any distance from the charge causing the field.

## What is electric flux and its unit?

Electric flux – Electric flux is the measure of number of electric field lines passing through any surface . It is a scalar quantity. It’s S.I unit is **volt meters**. Gauss Law- It is defined as the total flux linked within a closed surface is equal to the 1ε0 times the total charge enclosed by that surface.
