Let \(\mathbf{F}\) be a vector field whose curl and divergence at the origin are

\[
\operatorname{curl}(\mathbf{F})(0,0,0)=\langle 2,-1,4angle, \quad \operatorname{div}(\mathbf{F})(0,0,0)=-2
\]

Estimate \(\oint_{C} \mathbf{F} \cdot d \mathbf{r}\), where \(C\) is the boundary of the square of side 0.03 in the \(y z\)-plane centered at the ori
