Question

Post-lab Questions: 1. Archimedes Principle states that the buoyant force Fe acting on a submerged fluid is equal to the weight of the fluid displaced. Fs pVg. If the objects are regular in shape, by measuring the dimensions of the object and calculating the volume, one can determine the buoyant force that would be exerted on the object when it is submerged in a fluid of known density . Take one object with density greater than water from the box. Measure the dimensions and calculate the volumes. Using these volumes, the acceleration of gravity g and the density of water, calculate the buoyant force. Can you calculate the density of the object? Compare to accepted value.

Explanation / Answer

2 )

using the equation

density = mass per unit volume

when density is less so the mass of the air is also less for the given volume for the air compared to the water .

then can say the force also less by the air compared to water,

so we will not include the buoyant force is cause by dispalcement of air.
