. _ Sketch the electric eld around an innite sheet of charges. Set up a 3D coordinate system and pick one point (not on the sheet] and write down the Elec~ tric eld vector E at this point in proper mathematical notation if the surface charge density.r on the plate is {1.15 Cfmz. You \"happen\" to see another student's homework and notice that their nal answer for E is different from Yours! Is it possible that you are both right and will receive full marks, or must one of you be wrong? (Do not just state your answer but explain your reasoning.)
