I've uploaded a picture instead of writing the whole problem.
So the forces to consider here are - the weight of the cube, the normal force exerted on it by the funnel surface in contact, the centripetal force, and the frictional force.
If there is no relative motion between the cube and the funnel, then the net force must be the centripetal force. But I can't write out the force equations unless I know whether the frictional force points up the incline or down. I'm guessing it has something to do with ω but I can't be sure and I can't find the right logic.
I want to know if my assumptions are right and if they are, how are the friction and ω related ?
