Electric Field Vector

  1. Nov 2, 2015 #1
    1. The problem statement, all variables and given/known data
    From attachment R=-xaa-yay+3az

    2. Relevant equations


    3. The attempt at a solution
    I see 4 different values, one for each quadrant.
    1st.quadrant
    R=+xaa-yay+3az
    2nd. quadrant
    R=-xaa+yay+3az
    3rd.
    R=-xaa+yay+3az
    4th
    R=-xaa-yay+3az

    Where did I go wrong in determine value of R?

    The equation they gave applies to all 4 quadrants. It is just equal to minus a position vector drawn from the origin to any arbitrary point (x,y,-3) on the square sheet. The 3 unit vectors in their equation are pointing in the 3 positive coordinate directions.
