Question: Balls A and B of equal mass are floating in a swimming pool, as shown below. Which will produce a greater buoyant force? (Image shows two circles with circle A larger than circle B)
A. Ball A
B. Ball B
C. The forces will be equal
D It is impossible to know without knowing the volume of each ball
I think this question is poorly written. Based on the givens, I deduced that volume A > volume B, and thus density A has to be less than density of B in order for the two balls to have equal mass. So, the volume submerged in order for A to float has to be less than the volume submerged for B to float. Thus, it doesn't necessarily have to be ball A that will produce a greater buoyant force. Thoughts? Thanks.
