1.

volume of an object is 20 cm³ and the Mass in 50 G. density of water is one GCM -3. Will the object float on water or sink in water?

Answer»

Vol :- 20 cm
Mass :- 50 h
Density :- mass / vol
Density :- 50/20 = 2.5 g/cm
But density of WATER is 1 g/cm. HENCE the object will float. Since it's density is more than water.

Hope it helps you.
