A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 1.50 in the -direction experiences a force of 2.10×10?16 in the -direction, and an electron moving at 4.20 in the -direction experiences a force of 8.60×10?16 in the -direction.
a) What is the direction of the magnetic field? (in the -plane)
b) What is the magnitude of the magnetic force on an electron moving in the -direction at 3.40 ?
c) What is the direction of this the magnetic force? (in the -plane)
