Question
A vessel contains oil (density = 0.8 gm/cm3) over mercury (density = 13.6 gm/cm3). A uniform sphere floats with half its volume immersed in mercury and the other half in oil. The density of the material of sphere in gm/cm3 is :
Options
A.3.3
B.6.4
C.7.2
D.12.8
Solution
(C)
Weight = Buoyant force
Vρmg =
ρHgg + 
ρoil g
ρm =
= 7.2
Weight = Buoyant force
Vρmg =
ρHgg + ρoil g ρm =
= 7.2Create a free account to view solution
