The figure below shows equipotential contours in the region of space surrounding two charged conductors.

$($a$)W_{AB}$

The work done by any conservative force can be related to the change in an associated potential energy: $W=\frac{-}{{?}_{\frac{?}{?}}}PE.eV$

$($b$)W_{AC}$

$eV$

$($c$)W_{AD}$

eV

$($d$)W_{AE}$

eV
