A point charge +Q is located on the x axis at x = a, and a second point charge -Q is located on the x axis at x = -
 a. A Gaussian surface with radius r = 2a is centered at the origin. The flux through this Gaussian surface is
  a. zero because the negative flux over one hemisphere is equal to the positive flux over the other.
  b. greater than zero.
  c. zero because at every point on the surface the electric field has no component perpendicular to the surface. d. zero because the electric field is zero at every point on the surface. e. none of the above.

Question 2

A point charge is located at the origin. Centered along the x axis is a cylindrical closed surface of radius 10 cm with one end surface located at x = 2 m and the other end surface located at x = 4 m. If the magnitude of the electric flux through the surface at x = 2 m is 4 N  m2/C, what is the magnitude of the electric flux through the surface at x = 4 m?
 a. 1 N  m2/C
  b. 2 N  m2/C
  c. 4 N  m2/C
  d. 16 N  m2/C
  e. The correct value is not given.
