Answer 2

an iron ball will sink in water

Explanation;-

• The density of the iron ball is high as compared to that of water.
•  By Archimedes' principle - "The buoyant force experienced by an object is equal to the weight of water displaced by it ".  
• The weight of water displaced by the iron ball is less than its weight.
• So, the weight of iron ball exceeds the buoyant force. Hence, it sinks into the water.
