Homework Help: A stream of protons and electrons

  1. Oct 23, 2012 #1
    A stream of protons and electrons are shot horizontally (from the left edge of the page to the right) with a speed of 1.2 x 10^6 m/s. A magnetic field is oriented perpendicular to this motion (upward, out of the page) with a magnitude of 1.225 T.

    What is the radius of the curvature and the direction for the curvature that each of these particles undergoes?

    I do not know what formula/law that I need to use for this problem.

    Any help would be appreciated!

    This is not Advanced Physics (read the sticky thread at the top of the Advanced Physics forum for clarification on this). Thread moved.

    Have you tried looking up the law that describes the force experienced by a charged particle in a magnetic field? It should be in your notes or textbook.
