A uniform magnetic field B with magnitude 1.2 mT is directed vertically upward throughout the volume of a laboratory chamber. A proton with KE 5.3MeV enters the chamber, moving horizontally from south to north. (Mass of proton is 1.67x10-27 kg, ignore Earth's magnetic field)
(a) Find what magnetic deflecting force acts on the proton as it enters the chamber?
(b) Calculate the acceleration of the proton in the chamber?
(c) Suppose the proton enters the chamber vertically downward, opposite the direction of the magnetic field, calculate what magnetic force acts on the proton?
