A metal block of mass 1.560 kg is hanging from a string. The tension in the string is 7.185 N. The block is submerged in a beaker of fluid and is stationary. What is the magnitude and direction of the buoyant force acting on the block? Consider making a free body diagram showing the three forces acting on the block.
