Ninth physics problem buoyoncy

  1. Oct 3, 2012 #1
    This is a problem in ICSE (INDIA ) Concise physics text book.

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

    Answer given in text book is container will bounce back to the surface .

    Force downwards = m x g = Volume of container x density of container ( also = density of liquid A) x g
    Force upwards = Volume of container x density of liquid A *g

    since force upwards and downwards are equal , the container is to stay where it is placed .

    it is requested to please comment on this problem.
