A uniform magnetic field B, with magnitude B = 1.2 x 10^3 T, points vertically upward throughout the volume of a laboratory chamber. A proton with a velocity v = 3.2 x 10^7 m/s enters the laboratory moving horizontally from south to north. Find (a) the magnitude and (b) the direction of the magnetic force on the proton. The charge on an electron is 1.9 x 10^-19 C.
Given that the magnetic force Fm on a positively charged particle with charge q traveling with a velocity v in a magnetic field B is Fm = qLv x B, where the unit of B is Tesla (T), find the Tesla in terms of the following units: N; C, m, and $ or N, A, and m.
