Three blоcks оf equаl vоlume аre fully submerged in wаter.  They would normally sink but are suspended by strings as shown.   Blocks A and B have equal mass, and block C has more mass.   Blocks A and C have the same depth, and block B is at a greater depth.  The buoyant forces on blocks A through C are FA, FB and FC respectively. The tension on the strings for blocks A through C are TA, TB and TC , respectively. Which of the following statements are true?  State all that are true. For example, you might say "only c and d are true" then explain your reasoning. a) TA is less than TC. b) TA is less than TB. c) TB is less than TC. d) TA and TB are the same. Enter your answers below and explain your reasoning.
