These Gaussian surfaces consist of 5 different geometric shapes (A-Rectangle, B-right triangle, C- star, D- square, E- ellipse). Calculate the electric flux through each (15p) Gaussian surface. Please, Rank the Gaussian surfaces in order of increasing electric flux. A- Rectangle .-q D- Square E- Ellipse -39 +4q C- Star -39 + 9 -29 + 69 +59 B- Right triangle Good Luck
