Here is the MS: http://store.aqa.org.uk/qual/gce/pdf...W-MS-JUN11.PDF
Do they basically just mean find the tension ?

What does "the reaction of the bead on the wire" mean ? Is it the sum of the tension and parallel component of weight or just the tension or what ?

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

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.
5. 1 day revision... would it be possible to get a B?
6. I dunno,

Can anyone help me with this ?

Edit: Solved
