Answer
(a) $\int_CF.dr\lt 0$ and (b) The divergence is positive at the point P.
Work Step by Step
(a) From the graph we can see that the tangential vectors are making an obtuse angle with the vector field of all points on the curve. Therefore, $\int_CF.dr\lt 0$
(b) The divergence is positive at the point P.
Hence, the final answers are:
(a) $\int_CF.dr\lt 0$ and (b) The divergence is positive at the point P.
