(i) Accurately draw the field (both scalar equipotential and vector electric) lines between a positive point charge and an infinite grounded conducting plane. Briefly explain how your field lines correctly illustrate the nature of the field around the conducting plane.
(ii) By looking at your plot, write down the mathematical equation that describes the E-field for this point charge in this situation. Hint: derive it by only looking at the shape of the field.
