3. A point charge 40 is located on the x axis at x a, and a second point charge -O is located on the x axis at x--a. A Gaussian surface with radius 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 4. The electric field in the region of space shown is given by E (3i 2j) N/C where y is in m. What is the magnitude of the electric flux through the top face of the cube shown? 3m. a. 90 N m2/C b. 18 N m2/C c. 54 N m2/C d. 12 N m2/C
