A ground state Hydrogen atom moves at a speed of 4 km/second through a Stern-Gerlach magnet with a magnetic field gradient of 1000 Gauss/cm. What force does the ground state atom feel? How much does the field gradient accelerate the atom? How much does the field gradient deflect the atom? (The length of the Stern Gerlach magnet is 10 cm - that is the atom experiences the 1000 Gauss/cm field gradient for a distance of 10 cm as it travels through the magnet) I need some help getting started desparately...any feedback would be greatly appreciated.
