If a body will float on a liquid
Its density is more than the density of the liquid
Its density is less than the density of the liquid
Both has same density
Density cannot be determined
Unit of relative density is
g cm-3
g cm2
g m-3
No unit
Density of a liquid is measured using
Thermometer
Calorimeter
Galvanometer
Hydrometer
1kgf =
1 N
105 dyne
10 N
None of these
Floating and Sinking of an object depends upon
Density of the object and liquid in which it floats
Mass of the object and volume of the liquid
Density of the object and volume of the liquid
Both a and b
