The y-z plane at x=0 carries uniform charge density \(\sigma \). A unit point charge is moved from \((\delta , 0 ,0) \) on one side to \((-2\delta , 0 ,0) \) on the other side. If \(\delta \) is an infinitesimally small positive number, then the work done in moving the charge is?
1
\(\frac{\sigma}{\epsilon_0} \delta \)
2
\(\frac{3\sigma}{\epsilon_0} \delta \)
3
\(-\frac{2\sigma}{\epsilon_0} \delta \)
4
0
