Was there a criterion for choosing a particular vectorfield, since we were not given one? Thank you again!!!
Yes! The criterion is to use the vector you are given in the problem! You said, in your initial post, that you were to integrate the position vector over the surface of the cone. The position vector of the point (x, y, z) is the vector from the origin to that point: $x\vec{i}+ y\vec{j}+ z\vec{k}$.
