# Practising Gauss law

We have a charge $$q$$ placed at the origin in cartesian co-ordinate system.

Let the electric flux thorugh the surface defined as:

$$x^{2}+y^{2}=24, 1 \le z \le 5$$, $$x,y,z$$ in S.I units.

is given by flux $$= \dfrac{a}{b}\dfrac{q}{{\epsilon}_{0}}$$

Find $$a+b$$ where $$a,b$$ are coprime integers.

$${\epsilon}_{0}$$ is the permitivitty of vaccum.
