a brass spring weighs .83 Newtons while it is suspended in the air. next you immerse the ring in a container of light corn syrup. the ring appears to weigh .71 Newtons. what is the buoyant force acting on in the ring of light corn syrup?

The force of gravity on the object is the same all the time ... doesn't matter whether it's in the air, in a box, or in corn syrup.So when it's in corn syrup, the difference must be the buoyant force.  0.83N - 0.71N = 0.12 NewtonI'm sorry, but I just have to say how disappointed I am that you couldn't get through this one on your own.
