The liquid metal mercury has a density about
13.5 times the density of water. Consider
an object that floats in both water and in

In which case is the buoyant force on the
object greatest, and by how much?
1. It is 1/13.5 = 0.075 or only 7.5% as much
in mercury as it is in water.
3. It is precisely the same for both.
4. It is 13.5 times as great for mercury as for
water.
