Based on the figure below, explain which statement(s) best explain(s) the method to obtain electric field, E using Gauss's Law at Location A Location A Gaussian surface SG +psa (i) The cylindrical surface is chosen as a Gaussian surface SG, as it satisfies the symmetry condition of the +pga and -pgb shape. (ii) The spherical surface is chosen as a Gaussian surface SG, as it satisfies the symmetry condition of the +psa and -psb shape. (iii) A single Gaussian surface can be used for both surfaces to calculate E at Location A. (iv) Both charges must use separate Gaussian surfaces to calculate E at Location A.
