Homework Help: Potential between concentric spheres

  1. Apr 22, 2017 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations

    3. 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!
