question_answer
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? [AIEEE 2010]
A)
B)
C)
D)
Correct Answer:
C
Solution :
[c] so ball will not sink in water but sink in oil.
