A 5 kg brick is placed into a pool of oil with a volume of 100L. The 5kg brick rests on the ground of the pool and is 26.51N. This raises the oil pool level to 102.5L. From balancing the forces acting on the brick, calculate the buoyant force on the brick? Note: You cannot use the definition of the buoyant force since you do not know the density of oil. Now calculate the density of the fluid (oil) from the definition of the buoyant force? Show your work for full credit.
