What is the precaution to be taken in selecting the Gaussian surface, regarding the charge?
Dear Student,
Please find below the solution to the asked query:
Generally, you want to pick one with the same symmetry as the charge distribution, such that the magnitude of E is constant (or zero) over the surface. For spherical symmetry, this is a sphere: everywhere equidistant from the centre has the same magnitude E. For cylindrical symmetry, the surface of constant E is a cylinder. For planar symmetry, you usually choose a box with some of its sides parallel to the surface. For a plane parallel to the surface, the magnitude of E is constant.
Hope this information will clear your doubts about the topic.
