d) Compute $\int_{C} F \cdot d r$ where $\mathrm{C}$ is any curve from $(1,0,9)$ to $(1,2,2)$.
Final Answer: \(\boxed{\text{The problem is incomplete. We cannot compute } \int_{C} F \cdot d r \text{ without knowing the vector field F.}}\)
Step 1 :The problem is incomplete. We cannot compute \(\int_{C} F \cdot d r\) without knowing the vector field F.
Step 2 :Final Answer: \(\boxed{\text{The problem is incomplete. We cannot compute } \int_{C} F \cdot d r \text{ without knowing the vector field F.}}\)
