Essay

Let F=2xzi+5(yx)j+5xk { \vec { F } } = - 2 x z \vec { i } + 5 ( y - x ) \vec { j } + 5 x \vec { k } (a)Use Stokes' Theorem to find the circulation of F\vec { F} around the circle of radius a, r(t)=acosti+αsintj\vec { r } ( t ) = a \cos t \vec { i } + \alpha \sin t \vec { j } for 0 \le t \le 2 π\pi .
(b)Use this result to find the k\vec { k } component of curlF(0,0,0)\operatorname { curl } \vec { F } ( 0,0,0 )
