~~~~~~~FORCES!~~~~~~~~~help me PLEASSSSEEEE

Two books are stacked on top of each other on a level table. The mass of the upperbook is greater than the mass of the lower book. I wanna draw a free body diagram for each book. What forces are acting on the upper book and lower book?

I also have to rank all of the forces shown in the free body diagram i draw in order from largest to smallest. IF any of the forces have equal magnitude, iim suppose to indicate that explicitly. explain?

\begin{multline*}
\begin{split}
&Static\ equilibrium:\\
&Mass\ m_2:\\
&W_2=Fm_2m_1\\
&Mass\ m_1:\\
&W_1+Fm_1m_2=F_{m_1(table)}\\
&F_{m_1(table)}= W_1+ W_2\\
&F_{m_1(table)}= W_1+ W_2>W_2=Fm_1m_2=Fm_2m_1>W_1\\
\end{split}
\end{multline*}
