20. One kilogram of iron (density ∼7.8 g/cm3\sim 7.8 \mathrm{~g} / \mathrm{cm}^{3} ) and 1 kilogram of aluminum (density ∼2.7 g/cm3\sim 2.7 \mathrm{~g} / \mathrm{cm}^{3} ) are dropped into a pool, and they sink to the bottom. Which has the larger buoyant force on it? (A) iron (B) aluminum (C) both are the same. (D) neither has a buoyant force on it (A) iron (B) aluminum (C) both are the same.
