Given the potential field V = 100xz/(x2 + 4) V in free space:

(a) Find D at the surface z = 0.

(b) Show that the z = 0 surface is an equipotential surface.

(c) Assume that the z = 0 surface is a conductor and find the total charge on that portion of the conductor defined by 0 < x < 2,−3 < y < 0.
