You are completely immersed in water and then put on a lead "life jacket". How has the addition of the lead "life jacket" affected your overall buoyant force?
A) It increased.
B) It remained the same.
C) It decreased.
Solution: A. Buoyant force = Fb = ρfVdg. The only variable that changes is the volume displaced and it increases, so the buoyant force increases. Unfortunately, the lead life jacket increases the total weight force even more.
