1. The task is to figure out if the buoyant force is proportional to the mass of the object that is being sunk in the fluid (the fluid in this case water). I had an answer and that the buoyant force is proportional to the mass, but my answer only took into consideration objects with the same density. I am trying to figure out if the buoyant force is still proportional to the mass even though the objects that are being sunk don't have the same density. I have tried different ways to solve it theoretically, but have yet to find a solution 2. Relevant equations F=pgV, archimedes principle. 3. The attempt at a solution I tried to solve the question with a graph. Having the mass on the x-axis and the buoyant force on the y-axis. I still don't get any solutions and the graph doesn't really look right either. The formula on y=(x/p)* P* g, P is the density of the fluid, p is the density of the object and x is the mass of the object. I assumed the object would be dropped in water, so P=1, and g is of course 9.83. The equation became y=(x/a)*9.82. The graph showed that buoyant force was still proportional to the mass of the object, but I am extremely unsure if the way I did it was right or if it was the right answer.
