while pulling a bucket from a well the bucket full of water immersed fully in water appear to weigh less than when it has been pulled out of water .why
Answers
While pulling a bucket from a well the bucket full of water immersed fully in water appear to weigh less than when it has been pulled out of water, because of the upthrust.
When the bucket is in water, it experiences an upthrust in the vertically upward direction.
Thus, we can easily pull it in water, but once we take it out, there is no upthrust and appears heavier.
Answer:
While pulling a bucket from a well, the bucket full of water immersed fully in water appears to weigh less than when it has been pulled out of the water due to the upthrust.
Explanation:
The bucket full of water experiences buoyancy when it is in the water and hence is lighter. Once it is out of the water, the bucket is no longer acted upon by buoyancy and becomes heavier.
It is easier to pull the bucket of water from a well until it is inside but difficult when it is out of the water because upthrust acts when the bucket is underwater, and gravity acts when the bucket is out of the water.
The force pushes the object in the upward direction. Therefore pulling a bucket from a well, the bucket full of water immersed fully in water appears to weigh less than when it has been pulled out of water.
