WebDec 5, 2003 · That buyant force is being exerted by the water, so the change in the force on the scale is equal to the change in the force on the string. (*)Technically, there is a buyant force due to air, but it is so small that it is negligible in most situations. Dec 5, 2003 #4 cathliccat 8 0 I still don't know what to do. WebEssentially it's that simple. The reason there's a buoyant force is because of the rather unavoidable fact that the bottom (i.e. more submerged part) of an object is always deeper in a fluid than the top of the object. This means the upward force from water has to be … see when ice floats on water 11th part out of its remaining 12 parts remain in the … WebExplanation: The buoyant force is equal to the weight of the water displaced by the object.

The equation to calculate the pressure inside a fluid in equilibrium is: where f is the force density exerted by some outer field on the fluid, and σ is the Cauchy stress tensor. In this case the stress tensor is proportional to the identity tensor: Here δij is the Kronecker delta. Using this the above equation becomes: WebArchimedes’ Principle If we submerge an object in water, it will weigh less than it does in air because of the buoyant force. According to Archimedes this buoyant force is equal to the weight of the fluid it displaces.
