A rightward force $F$ can act at one of three points, $A,B$, or $C$ on an bent metal rod. The angle of the bends in the rod at points $B$ and $C$ are $45^{?}$, as shown. Rank the magnitudes of the torques about point $P$ if the same rightward force $F$ is applied at each of the points $A,B$, and $C$, (A means the torque about $P$ when $F$ acts at $A,B$ means the torque about $P$ when the same $F$ acts at $B$, etc.) $\begin{array}{l}C>B>A\\ A=B>C\\ A>B>C\end{array}$ $\times C>A=B$ $B>A=C$
