Question

with the help of an experiment show that an iron nail sinks and a cork floats when placed on the surface of water​

Answer 1

Answer:

A cork floats in water while the iron nail sinks because the density of cork is less than that of water. Thus, the upthrust of water on the cork is greater than the weight of the cork. Hence, it floats.15-Nov-2021

Answer 2

Explanation:

• A cork floats in water while an iron nail sinks because the density of cork is lower than that of water.
• Therefore, up thrust of the water on the cork is greater than its weight. Hence it floats.
• A piece of cork floats on water because the density of cork is less than the density of water whereas an iron nail sinks in the water because the density of iron nail is more than the density of water.
