(a) A particle with charge q is located a distance d from an infinite plane. Determine the electric flux through the plane due to the charged particle.
(b) What If? A particle with 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 charged particle.
(c) How do the answers to parts (a) and (b) compare? Explain
