Answer:
4N
Explanation:
From the problem statement, the weight of the piece of stone when fully immersed in water is 18N
The stone displaces water with the weight of 4N;
So, the weight of the stone in air is 4N.
- From Archimedes principle, we know that the weight of the water displaced when an object is placed in a liquid is the weight of the object.
- This method is often used to determine the weight of objects that are irregularly shaped.
- The weight of a regular body can be easily determined.
- But for irregular bodies, immersion in a liquid is a good approximation.
