Physics summer assignment vector multiplication

  1. Sep 2, 2008 #1
    1. The problem statement, all variables and given/known data

    In the product (Vector F) = q(Vector v) X (Vector B), take q = 2,
    (Vector v) = 2.0i + 4.0j + 6.0k
    (Vector F) = 4.0i - 20j + 12k

    What than is (Vector B) in unit-vector notation if Bx = By

    2. Relevant equations

    dot and cross products

    3. The attempt at a solution

    4.0i - 20j + 12k = (8ybz - 12zby)i + (12zbx - 4xbz)j + (4xby - 8ybx)k
