    Surface Integral

    I thought about doing the divergence theorem, but then quickly noticed nothign differentiated

    \iint_s F.n d\sigma F = zi + j -xyk and S is the surface cut from the cylinder  {y}^{2 } + {z}^{ 2} =1, z \geqslant 0. by the planes x =0, x=2

    F is solenoidal and applying the divergence theorem to that surface isn't a problem, so the outward flux is zero.

    So then the answer will be 0, because your integral will now be multiplied by 0?
