Planar motion:An electron enters a magnetic field of 0.7 T, moving perpendicular to it with a speed of 5·105 m/s.
a.) Find the radius of the orbit it will make.
Helical motion:
If an electron were sent at the same speed, but at an angle of 70o to the magnetic field:
c.) What would be the radius of the helical motion?d.) How long would it take for the electron to travel 3 m along ("downstream" to) the magnetic field?
e.) The "pitch" of a helix is the forward distance it travels during one complete turn of the helix. What is the pitch of this helix?
