Consider the field F = (x, y,z) and the cone z 2=x2+y2/a2- a. Show that when a = 1, the outward flux across the cone is zero. b. Find the outward flux (away from the z-axis), for any a>0. Therefore, the flux is zero. Interpret this result. A. The fluxes for x > 0 and x < 0 balance when a = 1, so the flux is zero. B. The field is parallel to the surface at every point, so the flux is zero. C. The fluxes for y > 0 and y < 0 balance when a-1, so the flux is zero. D. The field is normal to the surface at every point, so the flux is zero.
