how do we know the shape of gaussian surface to be use in which case

Expert Answer:

You are free to choose any Gaussian surface, but obviously you would like to choose one for which integration is easy to do. So we try and choose a surface which gives us a constant value of electric field so that we can pull E out of the integration and we only need to integrate over the surface, i.e. find the total surface area.
