Given:
The volume of wood is

The density of wood is

The volume of iron is

The density of iron is

The density of water is

To find the buoyant force on wood and on iron.
Step-by-step explanation:
The buoyant force can be calculated by the formula

Here, g =9.8 m/s^2 is the acceleration due to gravity.
On substituting the values, the buoyant force on the wood is

On substituting the values, the buoyant force on the iron is
