# Isolated Point Charge and Work?

This is a really abstract question, and I'm absolutely clueless on how to approach it.
I know W= F*d, where F=force and d=distance, as well as W= PEa-PEb.

The diagram shows an isolated point charge. Marked are four paths (A, B, C, and D) from a point (P1) to point (P2). The two points, P1 and P2, are equidistant from the charge. Rank the paths by the work required to move a positive charge from P1 to P2 from least to greatest.

For some reason I feel like B will be the greatest, but I don't really have any basis for that to be honest.

Welcome to the PF.

What have you learned so far about Conservative Forces and Conservative Fields?

We've learned about electric fields and electric forces. I know E= ΔV/Δx, where V is voltage and x is distance in meters. And E= F/q where F is force and q is charge. I don't have any notes on "conservative forces or fields" but that also might be just because my professor is using different terminology?
