Magnetic Forces Quiz I AM (name) __________________
Equations: (in your notes)
Hint: don’t mix up f and w
1. This problem uses vector notation. A pi meson (pion) is a particle that is created by the
nuclear force. Its symbol is + for one with a positive charge. A pion with
velocity (1x104 m/s i + 2x104 m/s j ) enters a magnetic field of (2T)j.
a. Describe the subsequent motion of the pion. (at this speed it lives around 1x10-8 s on
a good day)
b. Find the magnitude and direction of the force on the pion. Look up any data you
need.
c. Write the proof for the frequency f of the pion and calculate it with a calculator.
