In your Analytical Physics II Course next semester, you will have to calculate the force F applied by a magnetic field B on a moving charged particle q. This force can be obtained via the product F = qv x B. This force is being used in many electronic devices such as mass spectrometers. Given that q = 3, v = 2.0 + 4.0j + 6.0k, and F = 126 144 + 54.0k, what is the magnetic field B in unit-vector notation if Bx = By? B
