Three identical-sized blocks of lead, aluminium, and zinc are completely submerged in water. Given that, at room temperature: Density of Aluminium = 2.7 g/cm3 Density of Lead = 11.29 g/cm3 Density of Zinc = 7.13 g/cm3 How would the buoyant force on the lead block (BF)lead, on the aluminium block (BF)alum, and on the zinc block (BF)zinc compare with each other?
- 1(BF)zinc > (BF)alum > (BF)lead
- 2(BF)lead > (BF)zinc > (BF)alum
- 3(BF)lead = (BF)zinc = (BF)alum✓
- 4(BF)alum > (BF)zinc > (BF)lead
Correct answer
(BF)lead = (BF)zinc = (BF)alum
