SUMMARY

The discussion centers on solving for the magnetic field vector (Vector B) in the equation (Vector F) = q(Vector v) X (Vector B), where q = 2, (Vector v) = 2.0i + 4.0j + 6.0k, and (Vector F) = 4.0i - 20j + 12k. The user seeks assistance in determining (Vector B) under the condition that Bx = By. The provided equations include the use of dot and cross products to derive the necessary components of (Vector B).

Homework Statement



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

Homework Equations



dot and cross products

The Attempt at a Solution



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