The force of the repulsion of two charged particles is \[ F(x) = \frac{c} {x^{2}}, \] where \(x\) is the distance in meters and \(c\) a positive constant. Find the work required to increase the distance between the particles from \(3\, \mathrm{m}\) to \(1\, \mathrm{m}\).
\(\frac{2} {3}c\, \mathrm{J}\)
\(\frac{1} {3}c\, \mathrm{J}\)
\(c\, \mathrm{J}\)
