A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 1.20 km/s in the + x-direction experiences a force of 2.10×10-16 N in the + y-direction, and an electron moving at 4.20 km/s in the - z-direction experiences a force of 8.10×10-16 N in the +y-direction.
a.) What is the magnitude of the magnetic field?
b.)What is the direction of the magnetic field? (in the xz-plane)
c.)What is the magnitude of the magnetic force on an electron moving in the - y-direction at 3.50 km/s?
