Chapter 16.1, Problem 24E

Let $F(x)=\left(r^2-2r\right)x$ , where $x=\langle x,y\rangle$ and $r=\left|x\right|$ . Use graphing software to plot this vector field in various domains until you can see what is happening. Describe the appearance of the plot and explain it by finding the points where $F(x)=0$
