Two particles in a ring !

Hello,
I have a question about two particles in a ring.

Okay, so as far as I know the wavefunction of a particle in a ring is cos(kθ) with k=0,1,2,3...

So, what is the wavefunction (total one) for the two particles? Im guessing it must be the multiplication of the two:
totalphi= cos(kθ1)*cos(kθ2) Yes?

I've been asked what special care is needed when writing down the total wavefunction and i don't know what to say. Im guessing that you just have to consider them together yes? Or maybe repulsions?

help!

If there is an interaction between the particles, then indeed it will have to be accounted for.

I suspect however that the question was about the fact that care must be taken when dealing with identical particles to respect the Pauli principle.
