A rectangle block with dimension a*b*c floats on water. The block's mass density is a half of water density, so only half part of the block inside the water. See picture below.Find the minimum value of a/b in order to make it stable, if it's rotated slightly around axis O!

(Hint: if you understand the concept, it would be much easier)

I think it will be in stable equllibrium for any value of a/b.
