Question
A ball is made of a material of density $$\rho $$ where $${\rho _{oil}} < \rho < {\rho _{water}}$$ with $${\rho _{oil}}$$ and $${\rho _{water}}$$ representing the densities of oil and water, respectively. The oil and water are immiscible. If the above ball is in equilibrium in a mixture of this oil and water, which of the following pictures represents its equilibrium position?
A.
B.
C.
D.
Answer :
Solution :
Oil will float on water so, (B) or (D) is the correct option. But density of ball is more than that of oil,, hence it will sink in oil.
