Floating of a cork on the surface of water indicates that :

1. the density of water is more than the density of cork.
2. the density of water is less than the density of cork.
3. the density of water is equal to the density of cork.
4. the density of water plays no role in the floatation of cork.

The apparent loss in weight is equal to the upthrust on the body verifies :

1. Pascal's law
2. Newton's third law
3. Archimedes' principle
4. Newton's second law

Sinking of an iron nail in water implies that :

1. the density of nail is more than the density of water
2. the density of nail is less than the density of water
3. the density of nail is equal to the density of water
4. the sinking of nail does not depend upon the density of water
