Question
A vessel contains oil (density = ) over murcury (density = 13.6 g/cm3). Ahomogeneous sphere floats with half of its volume immersed in murcury and the other half in oil. The density of the material of the sphere in g/cm3 is
Options
A.3.3
B.6.4
C.7.2
D.12.8
Solution
Let density of material of sphere (in g/cm3) be ρ
Applying the condition of floatation,
Weight = Upthrust
or
or ρ =
= 7.2 g/cm3
Applying the condition of floatation,
Weight = Upthrust
or
or ρ =
= 7.2 g/cm3Create a free account to view solution
