An electron has velocity V = (29i + 38j) km/s as it enters a uniform magnetic field B= 50 i µT. What are (a) the radius of the helical path taken by the electron and (b) the pitch of that path? (c) To an observer looking into the magnetic field region from the entrance point of the electron, does the electron spiral clockwise or counterclockwise as it moves? The charge of an electron is -1.602 × 10-19 C and its mass is 9.109 × 10-31 kg.
