An electron is shot into one end of a solenoid. As itenters the uniform magnetic field with in the solenoid, its speedis 840 m/s and its velocityvector makes an angle of 30° with the central axis of the solenoid. The solenoid carries 4.5 A and has 8000 turns along its length.How many revolutions does the electron make along its helical pathwithin the solenoid by the time it emerges from the solenoid'sopposite end? (In a real solenoid, where the field is not uniformat the two ends, the number of revolutions would be slightly lessthan the answer here.)
