Problem: In a mass spectrometer, a beam of protons enters a magnetic field. Some protons make exactly a one-quarter circular arc of radius 0.50m. (B= 2.6 x 10-2 T and it takes the proton to complete the quarter circle in 6.3 x 10-7 s)
Part I: Find the net force (magnitude) on a proton while it is in the field.
I want help to find the net force (magnitude) on a proton while it is in the field and express your answer using two significant figures.
