Question

An empty container with its mouth closed has an average density equal to that of liquid. The container is taken 2 m below the surface of the liquid and is left there, then

• A. the container will bounce back to the surface.
• B. the container remains where it is left.
• C. the container sinks further.
• D. the container will move up and down.

Answer 1

The correct option is A

the container will bounce back to the surface.

The density of the object and the fluid is same. That implies that the weight of the object is exactly balanced by the upthrust. Hence the object will remain wherever it is being kept initially.
