(a) A point charge q is located a distance d from an infinite plane. Determine the electric flux through the plane due to the point charge.
(b) What If? A point charge q is located a very small distance from the center of a very large square on the line perpendicular to the square and going through its center. Determine the approximate electric flux through the square due to the point charge.
(c) Explain why the answers to parts (a) and (b) are identical
