Homework Help: Need verification of an equation

  1. Oct 25, 2015 #1
    1. The problem statement, all variables and given/known data

    Just trying to find an equation for buoyancy force.
    2. Relevant equations

    3. The attempt at a solution
    weight of an object in a fluid density of the object
    _______________________= ________________
    weight of the displaced fluid density of fluid

    weight of object x density of fluid
    weight of displaced fluid= ___________________________
    density of object

    Weight of displaced fluid=w1=buoyancy force

    It does not mention what the =buoyancy equation is. Archimedes principle is limited. I also went to the buoyancy page on wikipedia. not help.

    What is the formula for calculating the weight of a body? What's the formula for calculating the density of an object?

    Mass times gravity and mass divided by volume.
