Does the answer depend on RPM? If yes, what happens at 1 rpm and what
happens at 3 or 2 rpm?"

The site listed here

can give you an example of what happens to objects in a spinning habitat.

If spinward is to my left, and I toss a ball to you, in which direction do
you move in order to catch the ball? And the faster the spin, the greater
the distance the ball travels away from you.

But the basic problem of too rapid a spin lies in what it does to your
inner ear. Hard to get any work done if you're dizzy all of the time. Even
in a spinning habitat that doesn't bother you when you are standing still, a
sudden move in the wrong direction could bring on an attack of dizziness.

And the reason we can't say for sure what happens at 3 rpm or 2 rpm is that
we haven't tested it. Everyone reacts differently. At the other end of the
scale, 0 rpm causes one-third of people affected to become nauseous. So
it's anybody's guess at this point.
