1. The problem statement, all variables and given/known data 2. Relevant equations Work = - (integral of) (E dot dl) 3. The attempt at a solution Hi, I know that the right answer is D zero, but I fail to understand why. I said that the answer was A as I have different charges, and I thought that depending on how I approach each individual charge by taking either the left-hand path or the right-hand path that my integral of E dot dl would be different resulting in different amounts of work done. However, the solutions say that the amount of work done is the same regardless of path taken. Could anyone please explain to me why this is the case (with the electric field being conservative)? Thanks in advance for being willing to help.
