Question

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