The question from the previous page is reproduced below.

Two identical cubes $($D and E$)$ are placed in different liquids with different densities. After being released, the two cubes came to rest at the locations shown.

At the instant shown, is the buoyant force on cube D greater than, less than, or equal to the buoyant force on cube E$?$

We have been applying Newton's $2$nd law $(F_{\text{n}\text{e}\text{t}}=ma)$ in different situations$$ throughout this semester.

How would you apply Newton's $2$nd law to answer the question above about the two cubes in different liquids?
