A magnetic field of 2.00 T is applied to a bubble chamber to make the tracks of protons and other charged particles identifiable by the radius of the circles they move in. If a high-energy proton moves along an arc of a 3.30-m circle, what is the momentum of the proton? [q = 1.60 × 10^?19 C, m = 1.67 × 10^?27 kg]
1.06 C 10?18 kg / m/s
