## Homework Statement

The force on a particle is directed along an x-axis and is given by F = F

_{0}(x/x

_{0}- 1).

Find the work done by the force in moving the particle from x = 0 to x = 2x

_{0}

## Homework Equations

## The Attempt at a Solution

It looks like the force is a recurrence relation or something...

[itex]W = \int^{2x_{0}}_{0} F_{0}(x/x_{0}-1) dx[/itex]

I don't really understand.. unless I just take x

_{0}to be the lower limit of integration, 0, and then 2x

_{0}is just also 0, leaving me integrating from 0 to 0... which is just 0, but that seems to render this an absurdly stupid question.
