The whole question is in the attach figure.

Determine the surface fluxas E s dfor the vector field2 E a  E / R 0 Rfor thesurface defined by a planar circle of radiusa0 centered on the z-axis a distance z0 fromthe origin, as shown in figure (a) to the right.Write your answer in terms of the angle
