Work done = Change in potential energy (Uf - Ui)
Ui = (0.2 microC) (0.01 microC) / (4 x Pi x Epsilon x 0.1)
Uf = (0.2 microC) (0.01 microC) / (4 x Pi x Epsilon x 0.05)
Work done = Uf - Ui
= 0.00018 Joules
Ui = (0.2 microC) (0.01 microC) / (4 x Pi x Epsilon x 0.1)
Uf = (0.2 microC) (0.01 microC) / (4 x Pi x Epsilon x 0.05)
Work done = Uf - Ui
= 0.00018 Joules
