## Homework Statement

A large piece of cork weighs 0.224 N in air. When held submerged underwater by a spring scale as shown in Figure 13-27, the spring scale reads 0.672 N. Find the density of the cork.

## Homework Equations

Fb=buoyant force

## The Attempt at a Solution

i found mass by doing .224/9.8 so mass=2.286e-2 kg

then i got Fb by doing weight in air minus weight in water so Fb=-.448 N

then i did Fb=(densitywater)(volumeobject)(g) and got the volume of object so volume=4.571e-5 cubic m

last i did density=mass/volume and got the incorrect answer of 5000 kg/cubic meter

If anyone can help me, I don't know where I went wrong. Thanks very much, awe.g
