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. 2. A bubble chamber was an early method of observing elementary particles in the early 20th century early in the week. To learn more look below. a. Below is an example of pair production. A gamma ray uses E=mc2 to form an electron-positron pair. The image above shows pair production. For the image on the right, if the magnetic field points into the page, which is the electron and which is the positron? b. The frequency f of the spirals is found to be 2GHz. What is the strength of the field?
