Chapter 3, Problem 3.3P
Consider an electric dipole in free space, consisting of point charge q at location 2 = +d'2, and point charge -q at location z = -d/2. The electric field intensity in the xy plane is (see Problem 2.7):
where p is the radius from the origin in cylindrical coordinates.
(a) Determine the net electric flux associated with this field that penetrates the xy plane. (b) Interpret your result as it relates to Gauss’s law.

2) If the angle the displacement makes with the electric field is 0° it means the charge is moving
along (or parallel to) the field vectors. Is work being done? How will the angle here affect the
work done, explain your answer with a diagram?
