Two wooden boxes of equal mass but different density are held beneath the surface of a large container of water. Box A has smaller average density than box B. When the boxes are released, they accelerate upward to the surface. Which box has the greater acceleration?

a. Box A

b. Box B

c. They are the same.

d. We need to know the actual densities of the boxes in order to answer the question.

e. It depends on the contents of the boxes.
