11. A solid gold vase of mass 20.0 kg is suspended by a rope at sea bottom. What is the Buoyant Force of the seawater on the vase?
The Buoyant Force is given as follows:
where is the density of sea water, is the gravitational acceleration, and is the volume of the vase.
By definition, the volume is:
where is the density of gold, and is the mass of the vase.
Finally, obtain:
