Homework Help: Calculate the direction of the electric field (21.34)

  1. Oct 4, 2015 #1
    1. The problem statement, all variables and given/known data
    Calculate the direction of the electric field. There are four charges, each is at the corner of a square. One of the charges is -39 and the others are -27.7.

    2. Relevant equations

    3. The attempt at a solution
    I already got the right answer, but I don't understand the wording of the second option. What does "diagonal passed throw" mean? Thank you all very much.

    It's most likely a typo for "through". Passing through a point makes more sense.

    And is this question about Electric or Magnetic field? The title and your post seem to mismatch...

    Yes it should be electric field. Ah it's "through" not "throw" That makes more sense. Thank you again
