Finding the Normal Force of a block

AI Thread Summary
The discussion focuses on determining the normal force acting on a block sliding along a horizontal circular path inside a friction-free cone. Participants analyze the relationship between the normal force and gravitational force, concluding that the normal force can be greater than, equal to, or less than mg depending on the scenario. The consensus leans towards the idea that the normal force is greater than mg when the block is in motion due to the centripetal force required for circular motion. A request for a diagram to clarify the situation highlights the importance of visual aids in understanding the problem. Overall, the normal force in this context is influenced by the block's motion and the geometry of the cone.

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


Fn=mg if horizontal plane which means when on a tilted plane, Fn<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?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
