Problem 3: A beam of electrons travelling at 1.8 x108m/s is directed towards a 0.014 T magnetic field as shown in the diagram below. (K:1, 1:2, A:2, C:3) B X XXX XXXXXX XXXXXX X X XXX electron beam X A. Which of the following diagrams illustrates the path of the electron beam once in the magnetic field? (Circle one.) (C) X X X B X X X X X X X X X X X X X X X X X X X X XXX X X X X X X X X X X X X X X X X X X B. What is the magnetic force acting on the electron? C. What is the radius of the path of the electron beam while in the magnetic field
