Answer
In the diagram, we will illustrate the weight of the wood acting downwards due to gravity. This force can be denoted as ( W ) and its effect is shown by an arrow pointing downwards from the center of the wood.
Step 2

Answer
Next, we will indicate the buoyant force acting upwards, which can be labelled as ( B ). This force counteracts the weight and is shown by an arrow pointing upwards from the bottom of the piece of wood.
Step 3
Equal and opposite force vectors

Answer
Lastly, we will highlight that the weight and buoyant force are equal and opposite. Both forces can be represented by arrows of equal length in opposite directions, indicating that the piece of wood is in equilibrium while floating at rest.
