Answer #1

An electron follows a helical path in a uniform magnetic field
given by B→= (19 î - 59ĵ - 27k̂) mT. At time t = 0, the

electron's velocity changes with time. (b) Do its
speed changes with time? (c) Do its angle φ
changes with time? (d) What is the radius of the
helical path?

An electron is shot into one end of a solenoid. As it enters the
uniform magnetic field within the solenoid, its speed is 800 m/s
and its velocity vector makes an angle of 33° with the central axis
of the solenoid. The solenoid carries 3.00 A and has 8170 turns
along its length. How many revolutions does the electron make along
its helical path within the solenoid by the time it emerges from
the solenoid's opposite end? (In a real...
