JEE Main & Advanced Physics Fluid Mechanics, Surface Tension & Viscosity / द्रव यांत्रिकी, भूतल तनाव और चिपचिपापन Question Bank Pressure and Density

  • question_answer
    Three liquids of densities \[d,\,2d\] and \[3d\] are mixed in equal volumes. Then the density of the mixture is

    A)            d    

    B)            2d

    C)            3d  

    D)            5d

    Correct Answer: B

    Solution :

               \[{{\rho }_{mixture}}\]= \[\frac{{{m}_{1}}+{{m}_{2}}+{{m}_{3}}}{3V}=\frac{V(d+2d+3d)}{3V}\]= 2d.
