A proton is given kinetic energy of 0.200 keV.

(i). What potential difference was required to accelerate the proton from rest to 0.200 keV?

(ii). What is its velocity?

(iii). The proton enters a 10.0 mT magnetic field (~ 100x Earth’s field) oriented perpendicular to its path. Draw a diagram to show what hap-pens. Calculate the radius of the proton’s path.
