Homework Help: Theoretical Electric Fields Problem

  1. Jan 26, 2010 #1
    1. The problem statement, all variables and given/known data
    Field Lines Three Figure 23-64 shows the electric field lines for three point charges separated by a small distance. The two outer charges are identical and the one in the center is different.

    Figure 23-64
    (a) Determine the ratio, qA / qB, of one of the outer charges to the inner one.
    1Your answer is incorrect.
    (b) Determine the signs of qA and qB.
    qA 2Your answer is correct.
    qB 3Your answer is correct.

    2. Relevant equations
    (k * q)/distance^2 * unitvector pointing at point from source

    3. The attempt at a solution
    Uh Don't know how
