प्रश्न
A body floats in kerosene of density 0.8 x 103 kg/m3 up to a certain mark. If the same body is placed in water of density 1.0 x 103 kg/m3, will it sink more or less ? Give reason for your answer.
उत्तर
The body will sink less in water because the density of water (1,000 kg/m3) is more than the density of kerosene (800 kg/m3).
