Buoyant force on an object submerged in a liquid in equilibrium

See attached file.

To hold up a certain stationary iron anchor in air takes 200 newtons more than when it is submerged in fresh water. The density of iron is Di=7870 kg/m^3, and by definition, the density of fresh water is Dw=1000 kg/m^3.

Find the weight W, of the anchor in air.


Solution Preview

Step 1.
Recall that density of iron is mass per volume, Di= M/V and weight is mass times gravity field, W= M g. Combining these, we write:
(1) W = Di V g which can be seen from Fig. 1 of ...
