In a mass spectrometer, a beam of protons enters a magnetic field. Some protons make exactly a one-quarter circular arc of radius 0.50 m. a) If the field is always perpendicular to the proton's velocity, what is the field's magnitude if exiting protons have a kinetic energy of 10. keV? b) How long does it take the proton to complete the quarter circle? c) Find the net force (magnitude) on a proton while it is in the field.
