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

Correct Answer is : (BF)lead > (BF)zinc > (BF)alum

Three identical sized blocks of lead, aluminium and zinc are 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 lead block - (BF)_lead, buoyant force on aluminium block - (BF)_alumand buoyant force on zinc block (BF)_zinccompare with each other?

(BF)alum > (BF)zinc > (BF)lead
(BF)zinc > (BF)alum > (BF)lead
(BF)lead > (BF)zinc > (BF)alum
(BF)lead = (BF)zinc = (BF)alum
