    Electric field of a finite linear distribution of charge

    Hello! I do it for definition because Gauss's law not possible. I use cartesian coordinates: $$dq=\lambda dx'\text{because is only in x direction}$$ $$\vec{r'}=(x',0)$$ $$\vec{r}-\vec{r'}=(x-x',y)$$ $$\hat{r}=\frac{(x-x',y)}{\sqrt{(x-x')^{2}+y^{2}}}$$...
