SUMMARY
The electric field is not always zero within a Gaussian surface; it depends on the charge distribution and geometry of the object. For example, the electric field is zero at the center of a uniformly charged sphere, maximum at the surface, and approaches zero at infinity. A Gaussian surface is a mathematical construct used for simplifying calculations, and it does not inherently possess a zero electric field. In many scenarios, selecting a surface with a constant non-zero electric field facilitates easier calculations.
