A large piece of cork weighs 0.295 N in air. When held submerged underwater by a spring scale as shown in The figure shows that the spring scale reads 0.903 N. Find the density of the cork. (the spring scale is attatched to the cork from the bottom of the cork to the bottom of the water, so the force is against the buoyant force)
