Volume of an object is 20 cm3 and the mass in 50 g. Density of water is 1 g cm-3. Will the object float on water or sink in Water?
योग
उत्तर
Given:
Volume of object = 20 cm3
Mass of object = 50 g
Density of object = `"Mass of object"/"Volume of object" = 50/20` = 2.5 g/cm3
Now, we know density of water = 1g/cm3
Since, density of object > density of water, therefore the object is going to sink in water.
