If you're thinking about the bead being attached to the centre via a light rod, rather than being on a wire, then yes.
NOTE: I say rod rather than string since the reaction could be away from the centre if the bead isn't moving fast enough.
This question completely stumped me and I still don't get it. I can do all the maths fine but I have no idea what they actually mean by the normal from the bead on the wire.

Thnx
Draw a tangent to the circle at the bead, then draw the perpendicular to that tangent. And you now have the normal they are referring to.
Corresponds to the tension/compression in the ficticious rod of my previous post.
