The work done W=∮E.dl As the electric field is a conservative field, so the work done around the closed path will be zero. i.e, W=∮Edl=0

The work done $W = \oint E . d l$
As the electric field is a conservative field, so the work done around the closed path will be zero. i.e,
$W = \oint E d l = 0$
