A1.9-MeV (kinetic energy) proton enters a 0.29-t field, in a plane perpendicular to the field. what is the radius of its path?
Kinetic energy
KE=(1/2)mv2
(1.9*10^6*1.6*10-19)=(1/2)*(1.67*10-27)*v2
v=1.91*107 m/s
magnetic force =centripetal force
qvB=mv2/r
=>r=mv/qB =(1.67*10-27)*(1.91*107)/(1.6*10-19)*0.29
r=0.6867 m
For a proton
Magnetic field B=0.29T
Kinetic energy
K=1.9 MeV= 1.9*1.6*10^-19*10^6=1.6*1.9*10^-13=3.04
