So it doesn't matter whether it's a sphere or a cube (or even anything else), as long as a net charge of $q$ lies inside it, the total flux passing through the surface is $q/\varepsilon_0$. For an external charge the net number of field lines which go in or come out of the surface is zero and hence it's flux contribution is zero. For a charge inside the surface, the field lines either go out or come in depending upon the fact whether the charge is positive or negative respectively. When the field lines emerge from a point charge uniformly in all directions, the flux passing through any closed surface depends on the relative number of field lines which go into or out of the surface. This is based on Gauss's law for electric charges. The flux passing through any closed surface enclosing a net charge $q$ is $q/\varepsilon_0$. This is not only true for a cube or a sphere. If the Filters menu is greyed out, it's because your image is not in RGB mode. From the menus, choose the plugin you want to use. Why does electric flux through a cube is same as that of electric flux through a spherical shell? To use it, Open any RGB-mode image and select an area. For the tessellation, I simply adapted Florian Boeschs OpenGL 4 Tessellation to work with. Quick start When you invoke Flexify, a dialog box will appear: 1.

If you have PSP 7, look in Effects->Plug-in Filters->Flaming Pear->Flexify. For example, choose Image->Plug-in Filters->Flaming Pear->Flexify. Feynman explains the effect of the flux through a closed surface in a more complete way. This image shows how you can use a normalized cube to make a sphere. Use one of the 'Browse' buttons to choose the folder mentioned above. Note that this was a simplified adaptation from a chapter of The Feynman Lectures on Physics which explains why the images do not quite match my explanations since I was just talking about the top surface of the conical section being tilted.

Therefore the total flux flowing through the cube is the same as a sphere. Clearly the tilting of the top surfaces of these sections due to the fact it being a cube rather than a sphere does not affect the flux flowing through each area element. Now imagine splitting the cube up into lots of these conical sections. Therefore the flux through this surface is unchanged since flux is the product of the normal electric field component and the area. The area increases by a factor $\frac$, however the electric field vector in the normal direction $E_n$ is decreased by a factor of $\cos\theta$. Now imagine tilting the top of the cone by an angle $\theta$ so that the corners still lie on the conical section, as seen below: Since the electric field is parallel to the normal of the surface at all points, the flux is simply the electric field at that distance multiplied by the area of the element. Consider the flux through a tiny segment of a sphere.
