The figure below shows an antimuon (mass of 1.88 x 10 28 kg), initially at the origin of a coordinate system with an initial velocity v in the xy-plane. The initial speed is 5.15 x 106 m/s at an angle of 0 = 70.0° with the x-axis. The antimuon moves in the presence of a uniform magnetic field B in the positive x direction with a magnitude of 0.157 T and makes a helical path. The pitch p of the helix, shown on the figure, is the distance between successive complete turns of the helix, measured along the helix axis. 194 (a) What is the pitch p (in m) of the trajectory as defined in the figure? m (b) What is the radius r (in m) of the trajectory as defined in the figure? m Need Help?
