A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 1.70 in the -direction experiences a force of 2.10×10-16 in the -direction, and an electron moving at 4.50 in the -direction experiences a force of 8.40×10-16 in the -direction.
a) What is the magnitude and the direction of the magnetic field?
b) What is the magnitude and direction of the magnetic force on an electron moving in the -direction at 3.50 ?
