## Homework Statement

## Homework Equations

## The Attempt at a Solution

The energy eigen - value of a particle in a box is given by ## E_n = \frac { n^2 h^2}{8mL^2} ## .

Now, applying classical mechanics , ## \frac { p^2}{2m} = \frac { n^2 h^2}{8mL^2} ## .

## p \propto \frac { 1} L ## ,

So, the force is proportional to ## \frac { 1} L ##.

So, the answer is option (c).
