Consider the vector field F below.

WebAssign Plot

$($a$)$ Are the points P$1$ and P$2$ sources or sinks for the vector field F shown in the figure?

P$1$ is a sink. P$2$ is a sink.

P$1$ is a source. P$2$ is a source.

P$1$ is a sink. P$2$ is a source.

P$1$ is a source. P$2$ is a sink.

Correct: Your answer is correct.

$($b$)$ Given that

F $=$

x$,$ y$2$

$,$

use the definition of divergence to verify your answer to part $($a$).$
