Question

A boy floats in kerosene of density 0.8×10^3 kg/m^3 up to certain mark. If the same body is placed in water of density 1.0×10^3 kg/m^3, will it sink more or less?

Answer 1

it will sink less as density of fluid is less

Answer 2

The body will sink LESS in water .

◆Density of kerosene - 0.8 × 10^3 kg / m^3

◆Density of water - 1.0 × 10^3 kg / m^3

◆This is a case of RELATIVE DENSITY.

◆The body will sink less in water , as the density of water is more than density of kerosene.

◆We know , Kerosene floats in water as they have less density than water.

◆The more denser it is, more will be it's THRUST (upward force ) in water , so thus the body will sink less.
