Homework Statement
Consider the following statements for a particle in a ring. Determine whether each statement is true or false.

1.The energy levels are equally spaced.

2. The ground-state energy of the system is zero.

3.The angular momentum Lz of a particle is quantized with only possible values of mℏ, (m=0,±1,±2,…).

4. Energy transition that absorbs the photon of the longest wavelength is from m=0 to the m=1 level.

5. Ψ(φ)=cos(φ) is an eigenfunction of the kinetic energy operator T.

6. All energy levels of the system are degenerate.

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
