an object weighs 20 N. It displaces a volume of water that weighs 15 N.
what is the bouyant force on the object?
wut the heck?????????

The buoyant force is equal to the weight of the fluid it displaces. In this case, the object displaces 15N of water, so the buoyant force on the object is 15N.
This isn't to say that the object floats - the object weighs 20N, so there's a net 5N acting to pull the ojbect under water. But just because it's underwater doesn't mean that there's no buoyant force - it's still there and is why the object "feels" lighter underwater than it does out of the water.

i can't do the calculations in my head yet you should locate the density of the diver which you will get from the displacement (volume), and the mass. then you ought to study it to the density of salt water. the adaptation in the two densities delivers you the buoyant rigidity.
