The forces at work in buoyancy. Note that the object is floating because the upward force of buoyancy is equal to the downward force of gravity. In science, buoyancy ( /ËbÉÉª.Énsi, -Éntsi/ or /ËbuËjÉnsi, -jÉntsi/;) or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.
But the system given in the example was a rigid object. What about fluids? The answer may be known to you, liquids gain pressure with increasing depth because there is more bulk applying pressure(or force for that matter) from above. Hence dams have broader base and without protective gear humans can easily get crushed below a certain depth in water. Now, earth below the solid crust is magma, which is molten metallic mixture basically. So, a viscous fluid. Hence, does the density of earth increase with increase in depth. PS- upvote if helpful :P
