    Potential Spheres
AI Thread Summary
The discussion centers on calculating the electric potential V between two concentric spheres with a particle of charge q and mass m moving in a circular path. The user questions whether they can treat the spheres like parallel plates, using the relationship E = V/d, where E is the electric field. They also consider equating the electric force F = qE to the centripetal force required for circular motion. Concerns are raised about the impact of the spherical geometry on this assumption. The thread seeks clarification on the validity of these assumptions in the context of the problem.

Homework Statement


A particle charge q and mass m moves in a circle radius r between two concentric spheres which are a distance d apart, where d<<r. There's a potential V between spheres. Find an expression for this potential.

Homework Equations

The Attempt at a Solution


Can I assume that these are like parallel plates so that ##E = \frac{V}{d}##? The ##F = qE## and I can equate that to centripetal force. I'm just not sure if I can say that a sphere inside a spherical shell, which I assume is what the question means, would behave like that because of the curvature.

Thanks for any help!

That's what I would do.

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...
