A concrete block with a density of 8000 will sink in water, but a rope suspends it underwater underwater (that is, its completely underwater, not touching the bottom of the lake, and isn't moving. It measures 62 cm x 13 cm x 17 cm, and has a density of 8000 kg/m^3. The density of water is 1000 kg/m^3 Find the tension in the rope. Hint: Buoyancy problem - similar to the last problem, but add a rope pulling up
