Hello all,
I just received back a unit test on fields that I wrote two or so months ago (teacher marks really slowly). I did pretty well on it. There is one question that I lost marks on. It isn't terribly difficult, but my teacher hasn't shown us the correct answers yet and I want to confirm what I did wrong.

that is the scan.
i put two Fq vectors towards the charged plates and gravity down. it was the last question on the test, so i thought the magnetic field was there just to throw us off and i neglected it (i had another reason to neglect it that i can't remember right now)
