Static and Hydrostatic Issues


(1) One cube of volume 10cm³ weighs 50g. Placed in a water tank will it sink or float?

As the block density is greater than the water density, the block will sink.

(2) A 5cm³ ice sphere is placed in an aquarium with water. What is the force exerted by water under the sphere? Data: ice density = 0.92g / cm³ and water density = 1g / cm³.
