Question

Calculate the buoyant force of a piece of cork of 8cm3 that floats in water. Density of cork is 207kg/m3. ?

I need the mass, in order to get the volume to apply t to the Buoyancy formula of: B=(W)object=(m)object(g)

Answer 1

`0,0784N`

Explanation:

From Archimedes Principle, any object partially or totally submerged in a fluid is buoyed upwards with a force equal to the weight of the displaced fluid.

`therefore B=rho_(fl) V_(fl) g`

`=1000kg//m^3xx8xx10^(-6)m^3xx9,8m//s^2=0,0784N`

(assuming the density of water is at standard temperature and pressure, and that the cork is totally submerged as it floats in the water)
