| Mar 20, 2014 at 4:52 | comment | added | aukxn | so the the work here is the sum of all dot products of the $\vec E$ and the Infinitesimal "distance" (sorry I don't know what word to describe $\vec {dl}$) at all point on the path the charge take to move from A to B. That means it is $\vec E \vec {dl}$. It is hard to get the full detailed formula of Work. | |

This will make it that your integral is really are only summing the amount of the electric field in the direction of integration. Try googling line integrals for more info. | |
