    Two solids A and B float in water. It is observed that A floats with half its volume immersed and B floats with 2/3 of its volume immersed. Compare the densities of A and B

    A)            4 : 3                                          

    B)            2 : 3                                          

    C)            3 :  4                                         

    D)            1 : 3

    Correct Answer: C

    Solution :

               If two different bodies A and B are floating in the same liquid then \[\frac{{{\rho }_{A}}}{{{\rho }_{B}}}=\frac{{{({{f}_{in}})}_{A}}}{{{({{f}_{in}})}_{B}}}=\frac{1/2}{2/3}=\frac{3}{4}\]
