How Is Force Exerted by a Classical Particle in a Box Calculated?

[chaotic]

Homework Statement

how can we find the force particle exert on the walls for classical particle which is the infinite quantum well of length L and particle mass is m?

Homework Equations

E=h^2 pi^2 n^2 / (2ml^2) for quantum

The Attempt at a Solution

and F = -dE / dL = h^2 pi^2 n^2 / (m L^3)

 

[BruceW]

for a classical particle, you should just use classical equations. When an object bounces off the wall, what is the momentum being transferred?
