The actual weight of the stone is 11 N. It is based on the Archimedes principles.
What is Archimedes principle?
- Archimedes principle states that the up thrust by water on an object is equal to the weight of water displaced.
- Upthrust by water on an object= actual weight of object - weight inside water
What is the actual weight of the object, if its weight inside water is 9N and weight of water displaced is 2N?
Actual weight= weight inside water+ weight of water displaced
= 9N + 2N = 11N
Thus, we can conclude that the actual weight of the object is 11N.
