Finding the Normal Force of a block

[trivk96]

Homework Statement

And when the block is sliding along a horizontal circular path on the inside of a friction-free cone,the magnitude of the normal force (use the diagram)
1. is greater than mg, always.
2. is equal to mg.
3. may be greater than mg.
4. is less than mg, always.
5. may be less than mg.

Homework Equations

F=ma

The Attempt at a Solution

F_n=mg if horizontal plane which means when on a tilted plane, F_n<mg But in this case, the objects spins around which means it puts more force on the cone walls thus... more normal force. i believe it is 3. is this correct?

Can we see the diagram that you were using, or some crude replica of it?
