When an electron passes through the origin (x = 0, y = 0, z = 0), its velocity has components ofvsubx = 0 m/s, vsuby = +5000 m/s, and vsubz = 0 m/s. The only force acting on the electron comes from auniform magnetic field, which is in the positive z-direction and has a magnitude of 4.0 T.
a. What is the maximum distance the electron gets from the origin in its subsequentmotion?
b. How much time elapses before the electron passes through the origin again?
