How can we draw a two-object $FBD$ (Free Body Diagram) according to Newton's third law?

(N/A) To draw a Free Body Diagram $(FBD)$ for two interacting objects based on Newton's third law,follow these steps:
$1$. Identify the two objects involved in the interaction.
$2$. Isolate each object from its surroundings.
$3$. Draw the $FBD$ for each object separately.
$4$. Apply Newton's third law: For every action,there is an equal and opposite reaction. If object $A$ exerts a force $F_{AB}$ on object $B$,then object $B$ must exert an equal and opposite force $F_{BA} = -F_{AB}$ on object $A$.
$5$. Represent these force pairs as vectors on the respective diagrams,ensuring they are equal in magnitude and opposite in direction.
