Question

A charge q` is placed at the centre of a cube. what is the electric flux passing through the cube? solve
​

Answer 1

Answer:

As the charge is symmetrically positioned on each face of the square, the electrical flux flowing through each face is proportional to the 16th of the total flux. Hence, the electric flux passing through each face to the cube is q6ε∘.

Answer 2

Answer:

Electric flux, the property of an electrical field that can be thought of as the number of electric power lines (or electrical field lines) that intersect a given area. The negative flux is equal to the positive flux in magnitude, so that the net or cumulative electrical flux is zero.

We know that total flux passing through the cube is:

ϕ=qε∘ϕ=qε∘

As the charge is symmetrically positioned on each face of the square, the electrical flux flowing through each face is proportional to the 16th16th of the total flux.

Therefore, electric flux passing through each face

ϕ′=ϕ6=q6ε∘ϕ′=ϕ6=q6ε∘

Hence, the electric flux passing through each face to the cube is q6ε∘q6ε∘ .
