**1. The problem statement, all variables and given/known data**

Calculate the intensity of the electric field (in the origin of cartesian axes) created by 1/8 of a certain sphere charged with density of charge equal σ.

Answer:

[tex]\frac{{\sigma \sqrt 3 }}{{16{\varepsilon _0}}}[/tex]

**2. Relevant equations**

E = KQ/R²

Flux = Q/ε

E.A = Q/ε

**3. The attempt at a solution**

Well, I tried to calculate the electric flux in 1/8 of the sphere (see figure). Then, knowing the area of 1/8 sphere, we could calculate the electric field using gauss law. But, after all, the answer of the problem is different.
