Homework Help: Boyant force on an immersed body.

  1. Oct 11, 2016 #1
    1. The problem statement, all variables and given/known data
    The gauge pressure pg versus depth h is plotted in the figure for three liquids. For a rigid plastic bead fully submerged in each liquid, rank the plots according to the magnitude of the buoyant force on the bead, greatest first.

    http://file:///C:/Users/user/AppData/Local/Temp/msohtmlclip1/01/clip_image001.jpg [Broken] figure here: http://www.transtutors.com/question...n-fig-14-28-for-three-liquids-for--719045.htm

    2. Relevant equations
    Buoyant force= Vgd + pgA------ (1)
    p=pg + d.g.h ---- (2) p=pressure d=density of water g=gravity h=hight from surface
    3. The attempt at a solution
    then as h and pg increases buoyant force increase according to equation 1. Then the highest slope represents the highest boyant. a>b>c
    Is my answer correct?
