Simple Fluid mechanics problem

  1. Oct 22, 2013 #1
    1. The problem statement, all variables and given/known data
    A uniform wooden stick of density d is completely immersed in water of density D (D>d). One end of the stick is free to rotate about a hinge which is attached to the wall of the container. In equilibrium the stick the stick makes an angle θ then tanθ is-
    (a)0

    (b)d/D

    (c)1-d/D

    (d)D/d

    2. Relevant equations

    related to buoyancy

    3. The attempt at a solution
    First of all i am not understanding the nature of buoyant force. In this case can we consider it to act at the middle of the rod?
