Question
Rank the buoyant forces exerted on the following five objects of equal volume from the largest to the smallest. Assume the objects have been dropped into a swimming pool and allowed to come to mechanical equilibrium. If any buoyant forces are equal, state that in your ranking. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)(a) a block of solid oak
(b) an aluminum block
(c) a beach ball made of thin plastic and inflated with air
(d) an iron block
(e) a thin-walled, sealed bottle of water
Explanation / Answer
the buoyant force , F =gV
if all the materials have same volume , the buoyant force dipending on density of the materials.
the densities are :
solid oak - 705 kg/m^3
aluminum - 1522 kg/m^3
plastic - 849 kg/m^3
iron - 2100 kg/m^3
water - 1000 kg/m^3
the rank of buoyant force :
iron > aluminum > water > plastic > solid oak.
