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 4.60 in the -direction experiences a force of 8.40×10?16 in the -direction.What is the magnitude of the magnetic field? What is the direction of the magnetic field? (in the -plane) What is the magnitude of the magnetic force on an electron moving in the -direction at 3.60 ? What is the direction of this the magnetic force? (in the -plane)
