I need a little help with this question:(adsbygoogle = window.adsbygoogle || []).push({});

Calculate the work needed to move a 1.5uC test charge from point B to point D. (I have attached the diagram)

The first part of the question required me to find the electric field at the points A, B, C and D. Which I think I figured out ok.

I found Eb = 7.66 x 10^6 and Ed = 0 N/C

So I think the equation that I need to use is:

W = Fd

W = qE(dx)

whereq = 1.5 x 10^-6C and dx = 0.25m

I'm not sure how to figure out E in this case?
