A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 1.50 km>s in the x-direction experiences a force of 2.25 * 10-16 N in the y-direction, and an electron moving at 4.75 km>s in the -z-direction experiences a force of 8.50 * 10-16 N in the y-direction. (a) What are the magnitude and direction of the magnetic field

The plum pudding model of the atom state that ?
