Magnetic effect(jee)

An electron is shot into one end of a solenoid.as it enters the uniform magnetic field within the solenoid, its speed is 800m\sec and its velocity vector makes an angle of 30° with the central axis of the solenoid. The solenoid carries 4A current and has 8000 turns along its length. Find the revolutions made by the electron within the solenoid by the time it emerges from the solenoid’s opposite end.
