Let $C$ be a simple closed curve that lies in the $xy$-plane. Assume that the area of the region enclosed by the curve is 2. The curve $C$ is oriented counterclockwise when viewed from above. Use Stokes' Theorem to evaluate the line integral \ $int_C mathbf{F} cdot dmathbf{r}$, \ where $mathbf{F} = frac{z}{2}mathbf{i} + frac{x}{3}mathbf{j} + frac{y}{4}mathbf{k}$ \ (a) 0 quad (b) $frac{1}{2}$ quad (c) $frac{2}{3}$ quad (d) 1 quad (e) 2

5. Use Stokes' Theorem to evaluate the line integral ∫C y3 dx + 1 dy + (x + z2) dz, where C is the triangle with vertices (2, 0, 0), (0, 2, 0), and (0, 0, 2), oriented counterclockwise as viewed from above. Then verify Stokes' Theorem by evaluating the line integral directly.

$7-10$ Use Stokes' Theorem to evaluate $\int_{C} \mathbf{F} \cdot d \mathbf{r} .$ In each case $C$ is oriented counterclockwise as viewed from above. $$\begin{array}{l}{\mathbf{F}(x, y, z)=\left(x+y^{2}\right) \mathbf{i}+\left(y+z^{2}\right) \mathbf{j}+\left(z+x^{2}\right) \mathbf{k}} \\ {C \text { is the triangle with vertices }(1,0,0),(0,1,0), \text { and }(0,0,1)}\end{array}$$
