A group of particles is traveling in a magnetic field of unknownmagnitude and direction. You observe that a proton moving at 1.60km/s in the +x-direction experiences a force of2.10×10−16 N in the +y-direction, and anelectron moving at 4.40 km/s in the −z-directionexperiences a force of 8.30×10−16 N in the+y-direction.
What is the magnitude of the magnetic field?
What is the direction of the magnetic field? (in thexz-plane)  θ=
What is the magnitude of the magnetic force on an electronmoving in the −y-direction at 3.30 km/s ?
What is the direction of this the magnetic force? (in thexz-plane) θ=
