Question

the total electric flux through a cube when a charge 8q is placed at one corner of the cube is
​

Answer 1

Given ,

A charge 8q is placed at one corner of the cube

We know that ,

The electric flux passing through a cube when a charge is placed at one corner of the cube is

Φ = q/8Eo

Thus ,

Φ = 8q/8Eo

Φ = q/Eo

Extra Information :

Electric flux is defined as the total number of electric field lines passing through a given

It is denoted by " Φ "

Φ = EA

Φ = EA cos¤

Where , ¤ is the angle between electric field lines and area

Gauss theorem states that the electric flux passing through a closed surface or Gaussian surface is 1/Eo times the net charge enclosed by the surface

Mathematically ,

Φ = EA = q/Eo

Where ,

Eo = Permittivity of free space or vaccum
