In summary: The unit normal vector is easy to find. You can just use the parametrization of the circle to find it.

So would it be <0,0,sqrt(2)>?
Do I have to use polar coordinates?

This is getting a bit silly. Do you really have to ask whether <0,0,sqrt(2)> is a unit vector?

And before you talk about polar coordinates or rectangular coordinates, let's see what your integrand is. In post #15 we called the ##\vec V## the curl of ##\vec F## and the integrand is ##\vec V\cdot d\vec S##. What does that work out to?
